Hi MrsBrendanCole,
Wow that must have been some shock.
Just to hello, and that your description sounds just like my ds, and he is under assessmente and I know he is. My sis diagnosed him at 18m, but did not tell me and let me work it out myself, about 9ms later. But he is very mild on the spectrum, he did not start talking till 2y9m, at nearly 4 he doing incredibility well, if not a little repetitive sometimes. Before he could talk, he could still communicate his wishes, take your hand and guide you to the desired object/need (this is also an autistic trait). Always been clumsy.
He is very affectionate, loves hugs, and follows requests, infact always likes to help. He also knows when we are angry, sad and gets upset if we are and likes to make us happy.
He lines things up, colour sorts, currently into Ben 10 as his friends are (although still prefers his cars etc) and stuffing small items into larger ones.
Also friendly, likes people, but does not know how to interact with his peers, plays along side them, unless it chasing games, his v. good at that!
He has only fairly recently (well since the beginning of the year) develop a hearing sensitivity. He covers his ears to noises - baby crying, drill, hair dryer, liquidiser, motorbikes, lawn mowers. Hand dryers one of the worst and as he tells me everytime 'mummy do not use the dryer, dry your hands on your trousers' his idea. we are trying to work on this one.
This my still not be the case for your son, but it might be worth keeping a check on things. My son is my wold and a i would not change him at all. My ds is on IEPs at nursery and has come on hughly with a little help from staff (language and interaction), they have been fantastic and v. supportive and he loves them. If help is offered I would seriously consider it.
Good luck
