What typically happens with baby after birth?

First time being diagnosed with gestational diabetes and honestly my doctor’s office is pretty nonchalant about it. Some appointments they don’t even ask about my numbers. Fortunately it’s been entirely diet controlled so not too complicated but I asked today about what happens after birth and was provided with pretty much no information. So here I am…

Can anyone shed some light on what happens after baby is born? I read that they get their BG tested too but other than that I feel in the dark. Please share your experiences. Thanks!
