Guess who learned to wave today?

At church this morning I brought Duke in to the nursing mothers' room, and we saw my friend Jen. She looked at Duke and smiled and said "hello" to him, and he gave her a little smile and a cute little fingery hand wave.  Later on my parents stopped by our house briefly, and he waved to them 3 or 4 times.  It's so cute!  Little babies learning to wave...I don't think it ever gets old.

(And just so I don't forget to write this down, Duke is babbling a lot--mostly ma-ma, da-da, ba-ba, pa-pa.  Sometimes I'm beginning to wonder if he is actually saying "mama" to me, but I'm not yet convinced.  Duke is also rolling and scooting all over the floor.  He really wants to get moving!)
