Today was the first day that we've seen Karissa clap. It's was the cutest clap ever. She puts the back of her hand on one side of her cheek and claps softly with the other hand. So yes, it's a one handed clap. But it is the cutest one handed clap I have ever seen. I remember we practiced clapping with Ethan for months before it caught on. He didn't clap until he was at least 1, probably older. Karissa will be 9 months on Friday. I'm one proud mama!
