I am very worried about my 10.5 month old son. As a bit of background he was full term but was very upset for the first 6 months of his life - we think due to a dairy allergy and associated reflux which we have now fixed. As a result he didn't get much tummy time so his motor skills have been delayed - he is now just starting to try to crawl - rocking backwards and forwards on knees and can sit unsupported for around a minute. He loves standing and walks between me and my husband but is not yet cruising on furniture. My main concern however relates to his language skills as I think he is now making process with his motor development. He has never babbled and does not imitate at all. Even now he is often pretty grumpy and the majority of the sounds he will make are of the moaning kind indispersed with a few squeaks and squeals. It is really hard to engage him by talking, silly songs, expressions etc and he tends to get upset when I sit him down to try to read to him. He will sometimes turn to his name but does not point, waves or recognise words. He also has no stranger anxiety - often he gets more grumpy if I and in the room and engage with him. I was wondering if any of this could be related to autism however he does make good eye contact and loves more physical play and kisses and tickles will make him laugh easily. The other thing I have noticed is that he often has his tongue sticking out however he eats solids well so I don't think there is a motor problem. I have discussed this with my health visitor but she just wants me to 'wait and see' and puts this and his temperament down to teething - he has 8 teeth already and his molars are starting to come though - could this be the cause? I have also tried to talk to a couple of GPs but they keep referring me to the health visitor. I really don't know what to do - should I be worried about this?
