I've been somewhat worried for sometime about Sean's lack of speaking. But I'm reminded about how Liam usually speaks for him and my brother was the same way; I always talked for him so he didn't need to. Thankfully, Sean understands what we're saying to him "Get your shoes" etc and he does use a few signs "all done" to let us know what he wants. He says Mama, Uh-Oh, Ma'am, quacks like a duck when we ask him to say Duck and now he says Elmo. We rarely watch Sesame Street but he LOVES it. Scratch that, he LOVES Elmo...and that annoys my husband. But the kid likes what he likes.
Here's a short video of Sean talking...enjoy!
