How old was your child/children when you potty trained then?

My advise would be completely leave him alone about it. Let him see his brother go, and get praised. He'll come around he's ready. That is EXTREMELY early for a child to catch on. My daughter was actually 23 months when we was potty trained. My son was 26 months. He was like your son, he would scream and cry and didn't want to sit on it at all, but was very intrested when his sister would go. I stopped trying and left it alone. About a month later he came to me and said he wanted to sit on the potty. He didn't go the first time but I gave him a treat just for sitting there. Within a week he was telling me and is fully trained now. I find the more you push it on the the more they are discourages from doing it. Most of my friends little boys were not trained until around 3. Not because the moms didn't try but they just couldn't quite catch on. Don't be surprised if it takes another year. 3 is the average, some kids take even a little longer than that :)

well first you shouldn't be giving candy every time they go because that easily backfires, but honestly what i've discovered is that THEY have to be ready, and it will be easy to tell when they are- trying to force it on a kid that doesn't want to will only delay them further and then some parents don't realize that their child isn't the one potty trained- but they are, I've seen parents have alarms set on their phone to take their kid to the potty every 30 min and they would still have accidents but boast about their child being potty trained at 18 months- that is not potty trained. But you will find lots of people telling you that you have to wait for them to be ready and that is absolutely true. I only have two children of my own but I have worked at day cares and been around a lot of children.

Just relax about it, let the one who doen't like it stay in diapers, STOP giving candy to the one who succeeds, and wait until the other one is ready. most boys are not physically able to hold their bladder and bowels until they're at least two and a half, so it's very unfair to expect it of your son just because his brother happens to be ready.

As for your question - one of mine was a little over two-and-a-half, the other was about 22 months. In both cases I simply waited until they said they wanted to give up on diapers/nappies, and then they did it for themselves. 'Training' is a misnomer since you can't train a child to have bladder control. Once they do, it will just happen.
