Ok. I would advise the following
Wait for the NHS diagnoses as it will be more likely to gain any support that your child would be entitled to by law under something called an EHCP. ( google it)
meanwhile if it’s possible not to try and seek the answer without professional advice , but channel your energy to respond to what your child seems to need right now then that may help you feel a little more in control of the situation and help your child.
you can find so much information on the National autistic society website.
google it. Xx
If your child shows distress or Intolerance to certain foods or noises, touch, sensations ect…. Don’t force anything. Be your child’s advocate and support them to access alternatives. Or escape these situations … you can support your child to cope / find ways of managing in the future, if it’s in their best interest with professional help, for now just support what you see your child needs.
If there is any language delay you may like to print off some pictures and have them in a set place and take some out with you,
keeping them in the same place for your child to show that they need a drink, food toilet ect. These are sometimes called PECS ( incorrectly as that system requires a back and forth conversation via cards/ symbols) but they are correctly also just called symbols
to introduce them you would give it with the item it represents, eg show the drink card and if you can get your child to touch it then give them the drink. works best if you start with things your child is really keen to get , eg picture of fav toy.
every child and adult on the spectrum is an individual and it is hard to predict any outcomes.
but what is fundamental is a proactive family, that are able to make the adjustment the child needs and advocate and sadly fight for what they need
