hello all, I have posted on here before so sorry to post again but am getting increasingly worried about my 15 and a half month old son. This all started at about 3 months when for about a 3 week period he seemed to be determined to avoid all eye contact, however this quickly rectified itself and he is now a very sociable little fellow. However I cannot shake my concerns, mainly as at 15 months he still only has about six words excluding mama and dada, the most important words to him are "more" and "there", the latter when pointing at things. he hardly ever says mama and dada - he usually only says dada when his dad returns after a few nights away with work.
He does point and say "there!" when he wants to show you something interesting like an animal, and he does clap, he understands everything you say to him and follows instructions. However he never brings a toy to share or show, or gives you anything without being asked to. He doesn't ask for things he wants by name, he just points to what he wants or in the case of food, points and says "more!". He plays sociable games, like peekaboo which he loves and initiates himself. He joins in with bits of songs that he can say, and says "boo" when playing peepoo and "wheeee!" when on the swing. He can make the right animal noises or vehicle noises when asked.
I think another concerning thing is his fondness for spinning objects, which can preoccupy him for a while, or throwing things across the floor and following them only to throw them again. However he does have other interests and does respond when you call his name.
Finally, he's not that fond of waving although he does do it sometimes, rarely. And he still doesn't walk as his main mode of transport- he prefers to crawl, and when he does walk he can fall down quite often.
I have spoken to the hv who says about how this is well within the normal parameters, but isn't that what they always say? Views or perspectives would be much appreciated, as well as suggestions as to what I should do. I'm scared he has asd.
