My doctor said that my baby was measuring just under 5 lbswhen I was 37 weeks. But when I gave birth at 39 weeks she was 6lbs 14oz :) she'll probably put on a little weight before you give birth! It'll be okay :)
I'm trying to do tummy time with her but she crys every time so I barely put her on her stomach. I have to start tho. her doctor says it makes her stronger and she can defend herself more. I don't get it but whatever lol
