Penny at 4 months

The big thing that happened this month is that Penny rolled front to back (January 30, so technically in the fifth month, but close). I started to lose my milk supply this month as well, which I think contributed to a fussier baby than usual. Once we started supplementing, she went back to her sweet self. She was sleeping through the night until we went to California right before she turned 4 months, and she hasn't done it since!
