Re: newborn eats for more than an hour and a half at a time
If your LO screams every time you put him down, I would try never putting him down. Both my kids wouldn't tolerate being put down in a stationary crib. They'd start fussing within a few minutes. So I either carried them around in a sling or put them down in a swing- my eldest napped in the swing until she was a year old!
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
