hey there, firstly i want to give you totally unMNetty . I remember the feelings of realisation that all was not well, the crippling fear of the 'A' word.
Quite honestly? yes it does rather sound like autism with a touch of dyspraxia. But its really NOT the end of the world, honestly its not. If you had one wish for your child what would you want? 99% of mums would wish for happiness - and he DOES sound like hes a very happy little chap.
FIrst port of call is a referral from GP to paed, and take it from there.
THEN, take time for yourself and go easy on yourself. Its easy to get all caught up in therapies and therapists, places to go, people to see, methods to try, things to avoid - forgetting that you need time to get your head around it all. Try to stay being his mum and not his carer and enjoy him for who HE IS, not worrying about who HE ISNT, i understand thats easier said than done of course.
When the panic has subsided and life has settled a bit, you will find that you can look at your son objectively and see what he needs help with rather than trying everything and wearing yourself to a frazzle and accomplishing nothing but creating headaches!
THere is a whole wealth of info here, and the ladies here are wonderful, always with great advice, an ear for proud mummy moments (which we all love to hear, and you too will have them!) and a shoulder to lean on when you need it.
I am a mum to 5 sons. DS1 has ADHD and dyspraxia (amongst others), he could fall over the pattern on the carpet! DS2 has very mild ASD and dyslexia. DS3 is NT (tho is very often the worst behaved!). DS4 has Aspergers Syndrome and specific language impairment. DS5 is only 3.2y but has autism, GDD (functions as a 12mth old) dyspraxia, has little understanding, and is non-verbal.
I knew that DS5 was autistic at 18mths. when he was 2 the speech therapist at the time said "theres only 3 reasons a child would stop/regress in development 1) head trauma 2) epilepsy causing head trauma 3) an autistic spectrum disorder. Not counting rare chromosomal/genetic degenerative causes". I feel that the loss of pointing would fall into category 3.
On a positive note: I feel that your sons speech and understanding are extremely good signs. DS5 was very much 'locked in his world' but with gentle but persistant playing and 'intrusion' has worked wonders, not only for my child but many children. He is a very affectionate and loving child who brings me things (not always to play together, but hey its a start!), something i wouldnt have believed a year ago. It does bring me hope for the future. Autism is just a word, not a sentence. XXX
