Sorry for the delay everyone - half term - need I say anymore 
Wow, I don't know where to begin. Coffpot, good idea about the Gp and out of area, but surely the paed could have done that for us if it was possible? Alfie's problems with food - well he has about 8 foods which we call his safe food, when he gets stressed or we introduce new food he drops something from his list.
He is very orally sensitive, will only eat raw veg and nothing which he would see as mushy yet he will eat grapes - only green though, Apples and grapes have to be green (I know that's the autism though) beige food, dry cereal, dry everything, plain pasta, bacon. Oh he loves sal everything has to be salty.
He is huge on smells. Smells and sniffs everything - also hates messy things and messy hands. He won't eat anything that changes texture for example a chocolate which has a cream in the middle is a no no - separate he would have eaten them but not if they change.
He has only ever (since a baby) drank water in the same bottle (bloody Evian bottles) and only now he is being forced to have these calorie shakes will he have milk and it takes us about 2 hours to get him to drink 1/3 of it.
If we introduce new foods, he shakes like he is having a fit, cries uncontrollably and gags until he is physically sick.
We also have the added complication of gastric issues - he has reflux and if he doesn't eat or eats too little (only has small portions anyway) then he will be physically sick in the morning until about lunch time. Paed said he has too much acids in his stomach.
Sensory side of things - well as well as the above he is a sound seeker (according to specialist SALT) and will hum, cluck, cough and other stims if it's quiet. We have to always have the radio on in the car and during his SATS he coughed repeatedly all the way through (forced cough like your clearing your throat) he however, doesn't like noise so if the hoover is on will cover his ears, hates loud noises and doesn't cope well with it. He also has co-ordination issues and hypermobility which I believe can be a sign of spd also. He's also a hand flapper, jumper and twirler.
Bet you're all asleep after that one?
