I took my 16 month old son to be weighed by the health visitor. Wasn't feeling concerned about his development until health visitor said his speech was delayed. He does only have about 5 words but babbles constantly. She said I should read to him more. I read the whole time - she said obviously not in the right way (???) He is very active - running around, climbing etc. He points the whole time and communicates very effectively by that means. Could it be that is taking the place of words? Am I a bad mother for not worrying until now?
