Basals vs Bolus on Pumps (Omnipod)

I’m father to a 3 year old T1 also. I’ll let you know what works for us, but as always…YDMV.

First, our first Endo team was worthless. They were OK with our sons BG’s being over 300 all day long…as long as he wasn’t Hypoglycemic (low BG) for liability reasons…so I took things into my own hands and brought his A1C down to 6.9.

However, our new Endo team recommended that I scrap my plan (honestly, I was OCD and spent probably 7 hours a day analyzing, tweeking, comparing data, etc.,). I had about 15 or more “basal programs” during the day…and although what I was doing was working, the logic behind it, and the sanity I was losing to maintain it, just made it impractical long term.

My new Endo team (Top 10 ranked national Endo hospital) emphasized the following things to us on day 1:

  1. Lose all the insanity that I created and create only a couple “basal” programs. For us, they recommended a .05/hr basal rate all day and dismissing the nighttime basal deliveries due to his dropping low during the night.
  2. After the basal rates are changed, focus solely on finding out the correct bolus rates for our son.

Keep in mind, a carb isn’t always a carb in that all foods can and probably will react differently in your sons body. I’ve painfully found this out. We found that frozen french fries, heated up in the microwave) caused him to have severe spikes, so we eliminated those from his food choices. We have 4 other sons in our house so going “carb free” wasn’t an option for us. He eats what our other children eat as well as some specific foods that he likes, which don’t wreak havoc in his body. Whatever we do, we just make sure we count the carbs and apply the appropriate bolus for each food.

My recommendation is to test each food individually. We spent multiple days allowing him to eat only a single food so that we could get a feel for how each food ALONE reacts within his body. Once we found this out, we were better able to combine the foods and predict what his BG’s are going to do…but keep in mind, you WILL see high spikes, even “HIGH” pretty often, with toddlers our age because they are growing, their bodies are secreting growth hormones sporadically throughout the day and sickness wreaks havoc on their bodies as far as BG management goes.

The MOST important thing is to find the correct basal rate. This means that his BG should remain LEVEL during fasting…if he’s going up or down, then the Basal rate is wrong. If his BG rises with a basal rate of .05, then he needs his basal rate increased to .10. If it’s dropping, he should have his basal suspended during that time since you can’t go less than .05. (As indicated earlier, we had been suspending our sons basal during the night because he was dropping low.)

After you find the correct basal rate, begin focusing on bolus rates. Bolus rates are what determine the “spikes” we see after our sons eat their meals. Basal rates won’t have any impact.

Here’s what we do to determine if our son needs a bolus rate change:

Let’s assume our son has an I:C of 1:30, and his BG at time of meal was 150

  • We annotate our sons BG (150), what he’s eating, when he was bolused, when he actually begin eating, and when the meal completed).
  • Then you WAIT 3 hours…during this time you will see some pretty big spikes! Even potentially above 400!! The concern, though, is what the BG is AT THE END of the bolus test…a 3 hour period. So from the END OF THE MEAL, count 3 hours and look at the BG. If it’s > 30 points higher, we DECREASE the I:C to 1:28. If it’s > 30 points lower, we INCREASE his I:C to 1:32.

It’s really that easy. We don’t get “HIGH” that often, and most of the time we are even able to stay under 300 post-meal, now a days, but this isn’t always the case…some foods to cause huge spikes.

Also remember to use the “Extended Bolus” functionality on the Omnipod for any foods that are high in fat / starch. For pizza/pasta, etc., We do a 50/50, or 60/40 ratio most of the time and extend it 2.5 to 3 hours.

If you have any specific questions, please always feel free to send me private messages! My wife and I don’t know it all, but we’re trying to learn more every day to make sure we are making the right decisions for our son. Not sure if your son is used to the “cyborg contraptions” yet, but ours is NOT. He is still screaming bloody murder every time we have to change out his CGM/Pod…can’t wait for that stage to pass because it breaks my heart every time I have to change them out. :frowning:

Stay strong! Remember that we have to remain sane if we’re going to help our sons, so do the best you can do every day and if you have bad days…FORGET THEM…and just focus on having a better day tomorrow. This is the single piece of advise that’s helped me most.

At our sons ages, we can expect BG’s to be wild and move like a roller-coaster…it’s just part of having a toddler with T1. All we can do is annotate, analyze and tweak at every turn to avoid CHRONIC HYPERGLYCEMIA WHILE AVOIDING HYPOGLYCEMIA.

One final point. Hypoglycemia is CRITICAL at our sons age. Given all the brain development going on, low BG’s can significantly impact our sons development/growth. So I’ve finally wrapped my mind around that fact and be OK with higher BG’s as a trade off of avoiding hurting his brain development. As long as the BG’s come back down after the 3 hour period following a meal, I just let the BG’s do what they’re going to do. If they don’t come down enough and they’re outside the 30 points, then give a bolus correction, then tweak the I:C up or down based on the test results. And I do multiple tweaks per day sometimes because my sons body fluctuates sometimes from day to day significantly.

One final point. AVOID bolusing your son BEFORE the 3 hours is up. Doing this will most certainly result in a low. Just let the Insulin do it’s work for the entire 3 hours and then apply a bolus correction if you need too. Stacking insulin in toddlers more times than not, results in LOW bg’s.

Hope this helps a bit, but as I said, I’m always here if you need to talk/share or swap information, or just need to find out what another parent with a toddler with T1 is doing.

Stay strong!

Find what food(s) your son likes, and feed him those foods. Always have alternatives that he will eat to fill the carbs in the even he doesn’t want to eat what’s been prepared for him.

For instance, I know my son likes “cheese crackers”. For last nights meal, we bolused him for his food which included some mixed nuts which he usually likes. Last night he didn’t want to eat all the nuts. We estimated the leftover nuts he did not eat was about 4 carbs. So we gave him the equivalent carbs worth of cheese crackers.

This isn’t “feeding the insulin” at our son’s ages. It’s making sure they don’t go low, which is most critical at our sons ages.

Tell your wife that my wife and I are here if you need/want to talk, discuss anything concerning dealing with T1 in a toddler.

My son was diagnosed last February when he was 2…he’ll have been living with this for a year this February 28th. We’re learning every day! But the advice given here has been spot on!

Get a stable basal rate (during fasting, the BG should remain level if the basal rate is correct), then focus all your efforts on getting bolus rates adjusted until you get the right effect (after 3 hours, the BG should come to within 30 points of your pre-meal BG.)

Good luck to you! We can do this!

Harold, these were two GREAT posts! I wish I had had something like that to read after my son was diagnosed (for his age level of course).

Hi Harold,
This is helpful advice. One thing I would add is that the best basal program is not necessarily what will be perfect in every situation, it’s what helps you be sane with the fewest number of interventions. We too had something like 11 basal programs at one time. We now have 5. Even if they’re not perfectly optimized, it actually results in better control because it’s easier to debug and make changes. We had gotten to the point where we were updating settings just once every three or four weeks, which is not enough with a toddler. So picking a basal program that is not a PITA to change I think is key for psychological reasons if nothing else.

Also, while we do want to avoid hypoglycemia in young toddler and I suspect there are some dangerous effects we haven’t fully discovered yet, studies don’t show any significant cognitive delays associated with mild hypoglycemia. And studies do seem to show reduced brain volume and modest but statistically significant cognitive deficits in children running chronically high blood sugars. While the standard practice now is to avoid hypoglycemia at all costs, I suspect in five years, with the advent of CGM, it’s just so easy to see a low coming and doctors will advocate being much more aggressive in targeting normal blood sugars. that’s just my opinion though. It’s also possible that new studies will reveal hidden dangers associated with transient hypoglycemia…but as of yet the evidence isn’t really there yet. I think how aggressively you target normal has a lot to do with how closely your son’s BG tracks with his CGM. We find ours to be pretty close, and CGM typically overestimates lows. So it may read 46 but a finger prick usually says 56, a 65 on CGM can actually be 78, etc. If your CGM is missing a lot of fast-dropping lows, then it makes more sense to be conservative.

Also, while some 300s are inevitable with a toddler, I may be going out on a limb here but I don’t think every day should feel like a rollercoaster. We have what I consider a “normal” now and while there are plenty of abnormal days, they feel abnormal, if that makes sense? In the beginning, every day felt like a rollercoaster and I thought it was normal, but that’s become less common. We still have wonky growth hormone spikes, sickness spikes, weird bouts of sticky lows, but I’d say we get about a week or two between those. And if I have more than four or five days of rollercoaster I go back to the drawing board because something is up and its a sign I need to change my settings.

Our sons sugars nearly ALWAYS (not every time, sometimes they stay around 200), but generally, they go above 300 after meals. But whether or not they go above 300 isn’t the important thing from everything I’ve learned. What is important is that the POST meal sugars are within 30 points (higher or lower) of the PRE meal sugars.

Our “roller coasters” are not as steep these days, but we still have them and they are unavoidable unless he doesn’t eat…which he has to do. :smiley:

We are constantly changing our program because we may have 2 days of beautiful numbers, then the next day it’s out of wack so we adjust IC/Correction Factor, etc., to get our targets fixed in on the NEW target. :slight_smile:

Obviously I don’t want to overstep my bounds here, but have you tried something like prebolusing for some part of the meal (say, giving 0.3 units about 15 - 30 minutes before he eats,) and then bolusing for the remaining 1.2 units as he eats?

It’s just that a little time to give a little bit of insulin a head start is really helpful. If we prebolus for every carb upfront we are then looking at a ticking time bomb and if our son’s fickle taste buds don’t cooperate we are screwed. Plus our son seems to have pretty slow digestion so a pre-bolus for the full amount means the insulin will run out on the tailend, leading to a post-meal spike 2 or 3 hours out.

But if we prebolus, say, 0.3 or 0.5 of the total 20 minutes in advance, then bolus for the rest as he eats, he will start dropping but it’s pretty easy to catch with pretty much anything he eats, so there isn’t the same urgency.

Seems like for your mental sanity you’ve decided to take a step back and not micromanage, so I totally get the impulse to leave things the way they are as long as he’s returning to range 3 hours post meal. But I think there might be ways you can really tame some of those spikes without dramatically messing with your sanity or increasing the risk of lows.

At least, that’s what we’ve found.

Thanks @Tia_G! We have done a bit of that, but not to any great length. We certainly pre-bolus every meal, but generally we do all of it up front, wait, then have him eat. Fortunately our son seems to always be hungry and always eats relatively quickly (under 15 min), so he doesn’t drag his meals out over a lengthy period of time.

Thanks for the info and it’s something that we will definitely keep in mind for the future! One can never have enough tools to try and hit this moving target.

Thanks again!

Great advice here for anybody, and any age!

IF he is eating all his food without a fuss, thank your lucky stars!!!
Today my son rejected his oatmeal because, and I quote “It doesn’t have a shark fin in it.” Apparently the swirl of molasses on top did not sufficiently resemble a predatory sea creature for his tastes, and he vetoed for 10 minutes.
This is why we no longer pre-bolus for the whole amount up front. His little shark fin protest was annoying but not scary cause he only had 0.3 on board, and it allows me to better react to his toddler shennaningans as what they are…just annoying age-typical behavior as opposed to a life-threatening emergency.

Definitely worth remember when that stage comes (I’m sure it will at some point!) Thanks as always!
