I wouldn't worry too much, as long as little one is attempting to say words (even gobbledeegook) and you are encouraging the words too by repeating the correct word they are trying to say, they'll get there in time. If you get little one checked by a professional and all tests come back fine then just keep up with the encouragement. Too often I overhear parents comparing the stages their children are at with an attitude that it's some kind of competition. It's not. Each child is different (desptie what health visitors try to say) and they will get to each stage of development when they are ready. Our 3 1/2 yr old is just beginning to come out of her shy self where it was quiet mumbles all the time and pointing at things to actual clear sentences well pronounced. No matter how we tried to get her to repeat things or ask her to name things she would just clam up. We took her for all the usual testing but everything came up ok altho they are continuing to monitor her hearing - she can hear fine but they can't determine whether there is any problems with directional hearing as she's too young but no one is overly concerned. One morning, recently, she came down for breakfast and just didn't stop rambling on about her favourite teddy wanting to share her toast, that his favourite flavoured jam was blackcurrant and that it tasted like jelly. Quite a surprise to those listening I must say!
