Difference between pregnancies

What were the biggest differences between your first and second pregnancies? Did you have any?
Did 1st trimester symptoms start sooner?
And did you have a different gender than your first?

Hi! Although I did not have diabetes when I was pregnant, I did have large babies. The differences for me were the first pregnancy, I was nauseated for 4 months, 2nd pregnancy had none!
1st child boy/2nd child girl
I gained a lot of weight with both
2nd pregnancy I started have early contractions around 22 weeks and to go on bed rest for a week and had to take it easy at work.
2nd child was 3 weeks early but weighed 9 1/2 lbs.
