With my first, I just picked her up, put her to the boob and she nursed like a champ. Then I changed her diaper and she slept straight through it. With my newborn (1 month today), I attempt to dream feed him and he wakes up. Then I change his diaper. He proceeds to stay up for 2 hours or more. It just seems like he wants to give in to sleep but keeps fighting it. There have been multiple days of staying up until 1 or 2 to try to get him back to sleep.
He also just went through his 3-4 week growth spurt and has what I think may be reflux and definately lots of gas, so there is that too, but even when he's settled and not troubled by gas, he just can't give in.
If you've had a similar experience, I'd love to hear your story or how you overcame it.
