The “baby” can now say moo. I’m not sure why it’s important or that I think it’s significant that a 11.5 month old can say “moo” when you ask “what sound does the cow make?”, but there we go. I also caught him nodding today like he was actually trying to say yes. I experimented with and observed what he was nodding in response to (when I say nod, he was kind of nodding his head but quite jerkily and if he was sitting down he would kind of bob his whole upper half up and down). He was apparently actually nodding to communicate yes. Woo, infant communication has been somewhat shaped and constructed in a way that adult humans can understand!!
