I have a new one too. Two half days last week, full time this week. He eats fine, and doesn't scream all day (maybe just half the day, lol). My problem is napping. He has such a loud scream, and he's really stubborn. He fell asleep with me while having his bottle, and immediately woke up when I stood up to take him to bed. It's been a long time since I've had a kid with a napping problem.
