What's a mom to do??

I love being a mom! I love my kids! I love the joy that they bring into our home. I love the sounds of laughter, I love the funny things that the kids come up with, I love it all.. Well, almost all... Lately our 4 year old angel has been going through some sort of power struggle with Dallas and I. We can't get him to do anything. We ask him to do something, and he will flat out tell us "no!" The biggest battle has been getting him to clean his room. It's not a new thing. My kids have always had to clean their own rooms and they do it every day. Lately however, Gavin has decided that he doesn't have to do it if he doesn't want to. Basically, he's decided that he doesn't have to do ANYTHING that he doesn't want to do. I will ask him to go clean it up and he will just go lay on his bed. The other day he was in there "not cleaning" and I told him that every toy that wasn't put away was going in the garbage. I gave him and hour then went in and filled 2 garbage bags with toys. He didn't even care.

Probably for the past 3 weeks, we have had the same battle every day. Today I asked him to pick up his toys and he refused, so I told him to go in his room and said that he can't come out till it's done. He was in there for a couple hours just playing, reading books, and laying on his bed. He didn't pick up even one thing so I set the timer for 30 minutes and told him that if his room isn't clean when the timer goes off, I was taking EVERY SINGLE toy in his room away. It wasn't even very messy. I could have had it done in 2 minutes. I thought he would go right in and clean it up, but he didn't. The timer went off, and he hadn't done anything. So, "What's a mom to do"?? I told him I would take the toys, so, I took the toys! I felt horrible but I have been so frustrated with him and nothing seems to work. Dallas and I bagged up every single toy in his room and locked them up in the basement. Gavin was really upset for about 10 minutes, then he got over it and now doesn't even seem to care. I think it's going to be a while before he gets any of them back. I don't know what to do with him!! He can be such a sweetheart, but he is so stubborn!! I am not one to spank or anything like that but nothing I have tried has worked with him. It might be time for some "Creative Parenting". I don't like being onry with him. I want to be positive, but I also need him to learn that he has to listen. HOW DO I DO THAT?? I'm sure I'm not the only one who has dealt with this kind of thing. I need suggestions! My kids are growing like weeds! They grow up so fast, I don't want to waste time fighting with them or being mad at them. I want to enjoy every minute that I have with them but It's my job to teach them. They are all so different! What works for one, may not work for the next. So far, I just haven't found what works for my little Gavin. I sure do love the stubborn little thing though!
