I really think this is a symptom of adjustment. It seems like he just wants to be reassured (over, and over, and over again sooooo late at night) that we're here and will come to him. Once one of us picks him up, he's generally happy as a clam and ready to smile beguilingly and laugh. He's so darn cute and charming and huggy that it's impossible to hold a grudge.
At 6 AM I was just getting him back to sleep when Norah woke up for the day. Poor Paul awoke a few moments later to the sight of all three of his family members crying. I'm feeling better now and my mom is coming over soon to let me nap. Bringing our kids home has really made me appreciate living nearby our parents. That offers some comfort these days when it just keeps snowing and snowing and snowing and I think about offers we've had to transfer to a warmer climate.
For those of you who have adopted, I would love to hear your strategies for getting your kids on a predictable sleep schedule without making them cry it out. At this point, I don't feel making Atticus cry it out would be the right thing to do. We're already working on establishing a concrete routine during the day and for bedtime and both kids currently sleep in our room. Bringing him into our bed helps a little bit but he still wakes up and wants to be held.
P.S. Above is one of the few moments when they both napped at the same time (in the bathroom). Did I race off to my own bed for a nap? Of course not - I ran to get the camera!
