Girls ?my daughter has been waking up at night for a month now, she only falls asleep between 4 and 6 am. She sleeps a lot during the day (but a 2-month-old should still sleep that much), although sometimes she doesn't sleep all night and wakes up at 12 pm and hasn't had deep sleep since then. She eats normally during the day with intervals of 2-4 (sometimes) hours, but at night she asks much more often because she is awake, but for the past few days she's literally sucking on my chest, so tonight she sucked all night. As far as I can see, there seems to be enough milk, I'm not an expert,
