T didn't really have words until 15 months; at the time I was a little worried, but he took off at 18 months and became a very good speaker after that. R doesn't have any words yet at 14 months (he tries to make animal sounds and "talks" all day) other than mama and dada but I don't even know if that's deliberate. I thought he'd talk sooner since he hears us jabbering away all day, but it looks like he'll probably be the same as his brother.
