Have you ever noticed how much babies smile in their sleep? Anthony does it all the time. When Amelia was an infant, around 2 weeks old or so, I commented to her pediatrician that the baby must be gassy because she was smiley. "She's just having sweet dreams,"she told me. I asked her more and she explained that she is a Hindu, and they believe that babies are dreaming about their past lives. I think that sounds way better than saying they are gassy!
