Luke has been quite vocal lately. Still won't say dada, as much as we (Jason) try, but he can squeal with the best of them.
He's been making a new clicking noise too - you may have to turn it up a bit to hear it.
And this was today - he's a genius child I tell you. (Ok, ok ... so he's actually been saying bababa all week, and this was a coincidence - but still pretty cool that I caught it on camera.)
