Four weeks old and smiling on cue now. This is a lot earlier than I remember Henry smiling. Lucy has been interesting in that way. She is definitely more opinionated that Henry ever was about a lot of things; sitting in her car seat, waiting for food, having gas, needing a diaper change. When she thinks something needs to be done, it must be done NOW! However, she is also the most consolable baby I have ever met. Two words and a pick up and she is certain you will fix whatever ails her.
