Ditto to what everyone else has said.

My first stop with my son was the community health centre through the local council who put us on to a paed. who specialises with ASDs and SPD (sensory perception disorder) and an early intervention centre.

Even if he is not diagnosed with a condition, it does sound like he could benefit from some occupational therapy and they can give you some strategies to deal with his sensitivities.

My son used to hug like a robot with stiff arms but now he seeks deep pressure and wants to hug a lot ! And be wrapped up and wear long sleeves and pants in 40 degree heat. He freaks out at shorts and tshirts. A lot of people poo-pooed me when I said I was worried about my son, including his father! but I went ahead and am so glad I did.

If he is diagnosed with something, you may be entitled to some funding from the federal government.

If there is a paed. that has been recommended to you, find out how long to get in to see them and then tell your GP that's who you want to see.

Good luck.
