This is common behaviours in a child with autism. Speak to health visitor or G.p and make a list of behaviours and concerns and even video shortly some of them to help as they may see something that doesn't necessarily stick out to you. For example I learnt all about "stimming behaviours" when the g.p told me to do this
Thank you! G.P was no help but the health visitor is coming to have a chat with me in two weeks time so hopefully get somewhere then !?
The health visitor picked it up pretty quick on a home visit and referred to the child development centre
Could be on the spectrum, could be behavioral for some reason, just go see an Occupational Therapist and get an eval done!
It could be so many things. As a mental health professional myself, I consider these social media posts the equivalent to getting information of Wikipedia. This could be due to a recent change in the kids life, autism, trauma, so many things. Speak to a few different professionals and get multiple opinions before you decide which one to work with
