Mom! Help ???? babies 5 months old second time already wakes up at night and cries, breast doesn't take, turns away and cries. The first time when she woke up I managed to put her down only on a T-shirt, rocked her gently and quietly sucked her breast. But this time it doesn't work, what could it be? Considering that when she woke up for the first time she also cried, turned away and then suckled well. SOS help ??????
