My son is 3 and these last few days be has been really playing up.

Hitting me, spitting at me, telling me to go away, grabbing things from the freezer when I told him not to and running round the house with it like it's a game till I snatch it off him and put it back and lock the door so he can't enter the kitchen, he sees me clean up toys and waits till I'm nearly done then throws them on the floor again so I then make HIM clean it all up instead of him just helping me.

Everything he does I immediately tell him to apologise, tell him what he's done is wrong and explain that only good boys get good things like a sticker, or a treat. I've taken toys off him if he's been really really bad but he doesn't care.

I'm a single mum, I've been with my son his whole life and never had a babysitter it's just me and him. He NEVER NAPS!!! So it's 12/13 hour days with him just me and him.

He goes to daycare 2 and a half days a week but he even plays up as soon as I pick him up from there.

What do I do????
