When does bad behaviour become a medical problem?

[Howmuch101]

My DS is an extremely challenging child that I no longer know how to deal with.

From the moment he gets up until the moment he goes to bed everything is an issue. Everything is on his terms. So wakes up: "I want a wee, I want a wee, I want a wee - on repeat no matter how quickly he's taken for a wee. The next then is breakfast. "I want shreddies, I want shreddies. No not like that this way, this way, this way". Etc etc etc.

He hurts his little sister (just gone a year) constantly. He snatches from her constantly. He snatches at nursery constantly and they too struggle to deal with his behaviour.

His worst behaviour is with me though. It started when he was about 14 months old really with snatching, hitting etc.

I am just at a total loss. I'm stressed whenever he is around as his behaviour shows no let up.

I am consistent with time out on chair. He just screams the entire time. Says sorry and seconds later is back at the snatching, hitting, hurting and nagging.

I praise good behaviour consistently.

I love him and my DD more than anything but this behaviour is out of control, stopping me from enjoying both of them and I'm now starting to scream and shout.

He's just turned three.

Please help.

Okay

First of all, does he get heaps of fresh air, can you get out to a park or open (safe) area for him to run and run and run at least once a day (nicer weather makes this more bearable with a wee one)

Lots of folk swear by a tramopline for getting rid of excess energy

Now, sleep - counter-intuitive but overtired children can appear to be just bursting with the naughty, find a minute (haha) to do a simple analysis, does he get a decent night's sleep, could bedtime be tweaked a bit maybe

Then - diet.... He might be reacting to something like the yellow e number (talking out of arse here) so have a think about overhauling family diet if you have the energy

Don't be afraid to ask Nursery for advice, perhaps his speech/comprehension could do with some support?

I do sympathise, one of mine was DREADFUL til Reception

Nb ofc naughty behaviour not naughty child

Thank you! Better day today - but not without challenge. I'll enjoy erasing through that info polter.

Thanks everyone.

I seem to have read Quietly's post differently to how the rest read it.
You don't learn different parenting strategies or techniques to fix or prevent, but to manage. A very few parents with 'difficult' children might do this instinctively enough that they don't even realize they're doing it, but the rest of us need a bit of help. There's nothing wrong with asking for help. I second the recommendation for parenting classes if you can, especially if there's an underlying reason for the behaviour. Typical parenting might work on a typical child, but it never did on mine.

Thank you Ninja. I will look into it.
