I agree that's a bit young. The Munchkin, who has an OUTSTANDING vocabulary for her age, didn't even start speaking regularly until the middle of her 1st to 2nd year. She would say syllables and small words and then one day busted out with full sentences.
Nicholas had dada down very early (of course), ball, go and no by that age. Everything else was just sound. He is developmentally right on schedule at 20 months with a mouthful of words and a desire to repeat EVERYTHING you say. (Oh, and I mean everything.)
Don't let another mother's comparisons drive you up a wall. She sounds just fine!!
