Feeling baby move

Laying in bed with Colby tonight and "Baby Blake" was moving a lot.  Finally I was able to get Colby to feel him move (btw - we don't know if it is a boy or girl just what the kids call the baby).  Colby actually thumped me and said "this is what it feels like" so at this point I knew he was feeling it.  Colby's excitement was awesome.  He kept saying "this is so exciting!!".
