Good night! Girls, maybe someone has it too, tell me?! The daughter hasn't woken up for 3 nights and isn't taking the breast. In the evening after bathing and massage she falls asleep and wakes up only in the morning. As long as I tried to wake her up, she didn't wake up and tried to put the breast in, but no way. ? I'm afraid that less milk will be left and it's not even established breastfeeding. And so I want this time to be purely breastfeeding ?? What can I do? Why doesn't the breast take so long?
