Re: Feeding all night
My guess is that this is either reverse cycling (days and nights swapped) or a growth spurt. Are you okay with co-sleeping? It was the only way I got any sleep when my kids were that age. If I tried to put either one of them in a crib or bassinet or whatever, they acted like I had laid them down in a nest of hungry crocodiles, and were up screeching within minutes.
You're doing great, mama. Just hang in there!!! And at 20 days you can start instituting a loose bedtime routine- around the same time each night, turn down the lights, turn off the music and tv, give baby a warm bath, nurse... It probably won't generate a great night's sleep right now but it will build good, predictable habits or the future.
