The World Is Their Toilet...

First I don't have twins, howver have two kids that can feed off each other's bad behavior. Do not punish the one that did nothing, that will blow up in your face. If they get into trouble for doing nothing, then what is the point of not just doing it anyway? Make sense?
Just because they don't go in their diaper does not mean they are potty trained. Potty trained is knowing the urge, going to the bathroom, waking up dry and being able to hold it until they are in the bathroom! I say they aren't there yet. If you have to go back to pullups and let them know until they are ready to be big boys they are back in them, period. Boys don't typically train easily or early so being close to three it isn't uncommon they aren't ready.

If you don't want to do pullups you need to really start working hard with them. You need to set a timer, every 40 minutes and hand hold them to the bathroom. Not only is what they doing gross it is unsanitary on so many levels, what is to keep them from pooping and playing in it? They have no consequences that matter and you need to take them to the potty every half hour throughout the day, no matter how much of a pain it is for you and teach them to hold it and go to the bathroom. I would go hard core on this and really drive the point home to them it is UNACCEPTABLE to urinate or poop on the carpet.
Especially if they know how to go to the potty and choosing not to out of being lazy.

Also for boys try a chart for behaviors, they like visuals and striving for something. So, every day they go to the potty willingly, without issue and do not pee on the carpet a happy face, for every infraction take it away or a frowny. Tell them they have to earn six smiley faces in a row and then maybe an ice cream or a reward that appeals to them. It is training and enforcing positive behavior. You don't have to do it forever, however with a four 1/2 year old boy I do know that he likes seeing his progress, can relfect back on a bad day with a visual!
Some carept cleaners can be toxic too and I see you have a 20 mos old.
If they both do the deed, they both have consequences. Find what matters, if time outs don't cut i, then try taking toys away for a day, losing increments off bedtime, etc. If they are running the show now you are headed to trouble later.

We haven't started the potty training yet because they just turned 2. But I have been dealing with them taking their diapers off and spearing poop all over the crib. So, I've been turning their pj's backwards. But that doesn't really help you.

I would start taking their toys away. Take away tv time, their favorite games or play time with friends. Or maybe even separate the two. I don't know if that's possible but I would be getting very frustrated if I was you. Good luck.

When this happened in my home I made the kids stay in the bathroom so they would be really close to the toliet and if they went on the floor or carpeting they were part of the clean up crew. I got serious about it and until they realized the damamge it was doing and I made them stay in a confined area. If this didn't work I made them go back to wearing pull-ups until I knew they were trained. to me it's better to be safe than sorry. Good luck- this is a hard battle to win.

Hi A.,
I thought I had potty issues :)
Well I haven't tried this piece of advice myself as I haven't needed to but I understand it works for poopy problems.Try taking them outside and spraying them down with a very cold hose (no bottoms on) with each offense.
I hope this solves your problem. God Bless You, L.

I have twin girls that just turned 3 and were potty trained at about 2 1/2. First let me say this, all of my twin mom friends told me I was crazy and to not even try to potty train until they were 3, but we did well with it.
It sounds like you tried all the conventional things for getting them to stop, I would focus on the positive with them. Set up a star chart, or something that they would like and tell them that for every hour they go without peeing on the floor they get a star and after so many stars they get a xxxx insert thomas train, or whatever here. You may have to start small and give them something for each star, like a couple of m&ms.

Once they get good with a few hours, make it for morning and afternoon and then day by day etc.

I have found that with my twins when I focus on the positive they tend to do better then punishing the negatives. I always feel like when I put one in timeout the other one goes, hey maybe I can get away with that, and tries it and then they are both in time out and I am trying to keep them separate and it is a nightmare.

I would definitly not punish the other one if he is not doing anything. If the other one is getting stars and treats, the one who is being defiant will want what the other is getting too.

I hope that all makes sense and is helpful for you, twin potty training is hard!!

Simply tell them that pee goes in the toilet. Monitor them closely if you can to catch them in the act. Even if you don't, when you find pee, make them clean it up and sit in time out. Tell them that big boys go in the potty only and if they aren't going to do that they get to go back into diapers (be ready to follow through incase they test you. Get the most horrid looking bulky and cheap diapers you can find, and at the same time take away any and all 'big boy' priveledges, like bike, video games, tv, whatever they enjoy that you can associate with being a big boy)

Yes, it is a case of little boy naughtiness, but this is one that I would put a stop to asap. Some people may think it's "cute" at 3, but nobody will at 13!

When mine were training/newly trained, I made sure to have them go in the potty several times during the day. Any time we switched activities, were on our way out of the house, before a snack or meal, I made them each go. Since they seem to know that what they are doing is wrong, perhaps they are calling out for attention. It may not be about the potty at all.
