of a mother of two. I know I'm not supposed to compare but...I'm going to!
Two things about Adin that make me do a happy dance:
He can put himself back to sleep. If I'm walking with him and he's getting nice and drowsy, I can set him down in his crib and his eyes may open briefly, then flutter shut. Erik was more of a screamer when he touched the crib which was very stressful.
I can take him to the child care at the YMCA and come back an hour later. To be fair, I joined the Y when Erik was closer to one, and so more of an age of stranger anxiety.
