My 3 year old son talks a lot. Too much some days! However, I have noticed that he often adds a b sound to the beginning of words. So for example he said to dh this morning 'Your balarm is going off daddy', instead of alarm. He seems to do it even with sounds he pronounces normally at other times so he doesn't say bapple for apple for example. I wonder if this is normal or something I should get checked out. Does anyone have any experience of this?
