What did your baby measure anatomy scan vs birth?

My nephew was a week behind at anatomy scan but was 7.5lbs at birth.

My niece was right on track and 7.3lbs at birth.

My daughter, who has Down syndrome was 3 weeks behind, came 3 weeks early and was almost 5 pounds at birth.

This baby is measuring 3 days behind. Should I expect a teeny tiny baby? I really want one below 7lbs, 7lbs is huge! My nephew was so big compared to my daughter, i don’t want a huge baby. I would have them take me at 38 weeks, but they’ll only induce at 39 🥺

So, how big was your baby at the anatomy scan and then at birth?
