Baby sleeping 9 hours

CC

The past few nights my daughter has been sleeping 9 hours. I’ve been waking her up at around 9 hours so that she can eat because my boobs are leaking and so I can change her. Should I be letting her sleep for as long as she will sleep?

I’m so grateful that she has been sleeping so well but I don’t want to shortchange her if she needs more sleep and I’m cutting her off so that my boobs don’t explode lol
