Girls, hi! ? Our daughter in this age doesn't eat anything but breast milk, she can have water, juice, fruit puree, berries, bread. Meat, porridge, vegetables and so on she doesn't eat, she won't even take a sip, everything goes past her mouth, maybe she is eating breast milk for sure, but I am already tired? all night on the breast, wakes up and looking for the breast, during the day too with the breast. Does anyone have the same? Give me advice please.
