I would discuss your 1st pregnancy history with your doctor and ask them your question about baby #2.
My My first was small but ##2 seems to be larger.
No I didn't have gestational diabetes, only thing I had going against me was she sucked me dry of iron and energy. I was in iron supplements the lady half of the pregnancy to prevent anemia
Did you have gestational diabetes the first time?
My cousins first was over 10 pounds and her second was only 6 pounds.
