Hi. I have posted here before with the ongoing potty training trauma so will now try to be brief. But am feeling at the point of meltdown where I am either going to punish DS or give up entirely. I have had it!
DS1 is 3.2 yrs. I have attempting to potty train since he was just over 2 yrs. I have tried every method known to parents, DS is not motivated long term by sticker charts or chocolate buttons. However I ended up giving him a little toy car every time he weed in the potty and finally he seemed to have cracked it - that is he would wee in the potty if he had no underpants on, if they were on he would wee in them. And not be bothered by it, so would happily sit in wet underpants and trousers. So we went back and forth a bit between no pants at home and pull ups when out, then graduated to putting him in underpants whilst out and also taking multiple changes of clothes. Because he just wets in them. I ask and ask if he needs a wee, wants to go to potty or toilet and he says no, no and then wees in his pants. I stay calm and reiterate where wee goes and to tell me he needs a wee but he still does it again and again.
Now poo is another story. I have him in no pants at home. I can tell he wants to do a poo, lots of dancing around, crouching, whining... Does NOT want to do it in the potty or toilet. If he's not desperate to go but I know a poo is due I can coerce him into sitting on the potty to try but he doesn't produce anything then. So cue 5 - 10 minutes of DS dancing around and me trying to encourage him onto the potty and then the inevitable happens, he poos all over the rug [two days worth of poo actually so you can imagine!]. And says "clean it up mummy"
and 
This is the fourth day in a row he does this, although I thought some progress was being made as he actually pooed a little closer to the potty this time and I imagined he might have been trying to make a dash for it but just missed. And I said "You nearly made it, let's try again tomorrow" and DS seemed pleased with this.
But then, this is what tipped me over the edge. I clean the poo from the rug and come back from tipping turds down the toilet to see DS full on peeing all over the rug and laughing. Not a small dribble/possible accident but a full bladder, hips tipped back, outpouring all over the rug. And I wanted to KILL him. But I picked him up, told him he made Mummy sad, very naughty to wee on rug. And made him sit in the kitchen while I cleaned up again.
I hate potty training and am at the end of my tether. Just wanted to share that.
