I just have to say that number one, this is normal. I think every mom I know has gone through this. Kids test limits, and want to win power struggles. Number 2, I don't think a child should be punished for having accidents. She is doing this for a reason, but come on, she is only 2 1/2. Just because she was potty trained, doesn't mean she is never going to pee her pants again. I think instead of locking her in her room (probably not a good idea) you can reinforce staying dry. I bought special Tinker Bell panties for my daughter, she picked them out, and she knew that when she could stay dry for one week, she would get the panties. She was 3 at the time. So, it was her decision that when she was ready, she would keep herself dry. Number 3, act like it doesn't bother you. Even if you are fuming inside because you have yet another mess to clean up, put a big grin on your face and say, "uh oh, looks like we need to get you cleaned up", or something to that affect. The more she sees that all of her antics don't bother you, she will eventually give up and start keeping herself dry. She is trying to push your buttons, and it's working for her. You can also make her a part of the clean up process. Make her carry her wet undies to the laundry room and put them in the washer. Have her help you clean up the puddle or scrub the carpet. Just keep in mind that she is only 2 1/2, and sometimes we parents set our expectations of our kids too high because they have reached a mile stone, like being potty trained before she was two. That's exceptional, but she still has a 2 1/2 year old brain, so of course she doesn't think to stop what she is doing to go to the potty. You should see my husband when he is looking up some electronics gizmo on the computer...he will squirm and bounce his legs until I finally say, "go to the bathroom", and he will be 46 in a few days! As far as dad's discipline, he is the one home with her, so he will be the one to learn how to discipline when you are not there. When you say lack of discipline, I can't really bash your husband for that because I'm sure he does his best. If you were home, I'm sure it would drive you nuts to have him come home and tell you how you disciplined was wrong, or that you didn't punish your child enough. You both need to stick to one type of consequence for certain behaviors, such as, if she throws a toy, the toy gets taken away. If she starts wiggin out and can't tell you or dad what's wrong(she has a melt down)put her in her room on the bed and tell her she needs a time out and you will be back to talk to her when she is calm. Of course, you two can come up with the right consequences for your own kids, these are just suggestions. You just have to make the punishment fit the crime, and be consistent with it. I have learned as my kids get older, their goal is still the same, they want to win the power struggle, we just have to be calm and very matter of fact and tell them the consequence, and follow through. Just as my husband and I learned how to work together when giving a consequence, you and your husband will too.
