H.W.
No concern-- I used to work with a toddler group of 20-30 month olds. Most kids did not have many words at all coming in... One little girl, I remember, pointed all the time to things and we would name them for her. She started talking at about 27 months and then, BAM! her language was unstoppable. Kids do this at different times. I think my own son was past two.. can't get him to keep quiet now. :)
Try to remember that developmental milestones are not set in stone, they are more like a 'window' where language is becoming emergent in some kids, but they don't really address the timelines of either early talkers or late talkers. And I've seen very intelligent children start out with what some would consider 'late' talking skills. Try not to worry, okay?
