My daughter literally won’t go to bed till after 5am, she will literally be breastfeeding all night.... she’ll fall asleep drinking and then when I go to move her she wakes up and cries and cries until she’s back on my boob.... my sons wake up at 6:30 every morning.... I don’t know what to do 😩 I know she’s a newborn and she doesn’t have a sleep schedule but it’s exhausting and I start falling asleep while holding her and I don’t want anything to happen to her that way
