Welcome to 3FC! We're glad to have you here!
Congratulations on your baby! If it helps at all, my mother had her last child at 42 years old, and she was able to lose quite a lot of weight afterward. She was definitely obese after the birth, but managed to adapt and made enough changes to lose weight. You can do this!
I think doing this for yourself and for your children is a good goal. It focuses on health above other things, and it sets a great example for your kids. There are a lot of resources and support here for you.
Welcome again!
