5 year old boy HELP!

[Wudgy]

My just turned 5 year old has suddenly got so “ cheeky “ in last few weeks and I need help responding!
examples that are new.. repeating anything I say to him in a mocking voice back to me in a na na na voice. Calling me stupid face, stupid etc- but also at any SlighT annoyance for example something falls, his sister annoys him.
generally not listening and just saying “no” if I ask him to do something or say ok it’s time to go let’s put on shoes etc...
no big recent changes to his company/ friends etc.but he had a few weeks of watching you tube minecraft videos so have nipped that out. I try not to give a reaction to the negative as I know what you give reaction to you’ll see more of but I can honestly say I am SO Triggered myself about him mocking me ( from my own childhood) .
also I was so cross my husband gave a big reaction to a new word he used yesterday as he heard someone on tv use it- wasn’t even anything too terrible but now son prob thinks oh ok store that up and use again.
attention I feel is some of the reason , but it’s this negative spiral of me finding it hard to spend dedicated 1:1 attention time with him as he is so draining ( I have other children) but then I know he would benefit from that connection .
sorry for rambling, heads a spin, try to do our best but sometimes think ahhh what to I do/ say here not to threaten/ shame etc as trying to break this cycle of how I was parented. So hard!

so if u got this far thanks, what’s something I should say/ do when he does the mocking thing or try to completely ignore?? Same with the calling me names?

i try to do you seem upset at me , help me understand why etc but sometimes I think I am FAILING !!

It's not your fault, 5 year olds do this.

On the repeating everything, normally I mock DS back for a little bit by making him say things he doesn't want to ('DS name really loves tidying his room, he is going to go and do it right now') then I get bored and ignore him, sometimes I tell him I'm bored and going to ignore him now, sometimes I just go to another room and start doing something else. Silence is also an effective way of baffling the copycat!

Otherwise you need some boundaries as to what you will and won't accept in terms of back chat, make sure he understands them, and apply whatever consequences you normally use. If DS goes too far he gets a LOOK and a 'you don't speak to me like that' and if he doesn't back off I start removing privileges.

DS is 6.
