My little boy didn't say much until he was close to 3. He would say one word things, but just wasn't a talker. I was worried too, and had both his hearing tested and had him evaluated for First Steps. The thing was though, he just wasn't interested in the one word phase. When they came to evaluate him for speech therapy, he said every word to every object she showed him. She was actually surprised at how many objects he knew, insinuating that most kids his age didn't know as many. My son has always been obsessed with letters and numbers. So, looking back, I just don't think that talking was a very big deal to him, so he waited until he was ready. He knew about 60 words at age two, and I think they want them to know 50. Your child is still very young to worry about it in my opinion.
All of a sudden at almost 3, my son just took off talking. Now, he's totally caught up. I don't think he was ever behind now, just didn't feel like using his words back then. Also, if it makes you feel any better, he's now a genius in the spelling department. He turned 3 in December and can spell words like "xylophone, umbrella, watch", so just remember that every kid is different. Some are early talkers, and some are interested in other things.
