Many parents get worried if their child is not speaking by one and a half years and because the neighbour’s kid was speaking at that age.
It is important to recall by which time the baby attained the other milestones like sitting, crawling, standing, playing with toys, etc. If all these have been achieved at the right time, there is no need to worry, as your baby may just be a late talker.
He may outdo many others later on and talk his head off. One thing you have to make sure is that he hears normally. Ask him to bring his shoes or a toy without pointing to these, or call him from the next room or switch on the radio in the next room and see if he responds.
You will have to test it several times because at times babies do not respond because they are absorbed in something else. If you have any doubt, consult your doctor. The often held belief that delayed speech is due to a tongue-tie, is not true.
