I'm really struggling and need some input please! I'd post on parenting but it's quiet and I feel I need the help quickly.
As background, I have three children; a 5 yr old, a 4 yr old and a 2 year old. They all get on very well with the 4&5 year old playing very well, they share a room and generally have a lot in common.
All of my children have generally had fairly laid back dispositions. No terrible twos and I could take the elder two out most places with no issues. They may cry occasionally if things didn't go their way but no real tantrums, all very mellow and manageable. My 5yo was always known for being relaxed, smart, and ab little reserved.
Sadly for me, the terrible 5s have seem to have started. He's progressively, over the past 3 months or so, become more shouty, rude and particular. He's started to hit me and gets very upset very quickly. He's always liked things a certain way but he used to be able to adapt and move on. Now, all hell breaks loose if he doesn't get his own way immediately. I'm on tenderhooks and feel very anxious now around him.
He has become fixated on detail and asks me over and over again to do something/ remember something /give him something etc. If I don't give him eye contact when talking, he'll throw a tantrum. If I don't repeat it back 100% correct, he'll lose his shit. And god save you if you interupt him at all.
I know this might sound insensitive to kids with autism, and I don't mean it at all, but it's genuinely like he's develop autism overnight.
Disclaimer; when he was a toddler, I would occasionally worry about autism. He would go through stages of no eye contact, obsessive body rubbing and also had speech delay, but except the speech, these were short phases that would come and go and generally no one, including family and his nursery, had any concerns.
What is this?! Is it "normal" or should I be worried? Should I approach anyone for help? It's getting to the stage where I'm becoming miserable and my anxiety is through the roof.
He's my eldest so I'm not sure if this is common or not or anything to worry about...
