Hello T., Your daughter sounds just like my oldest. I actually took mine to a child therapist at 3 yrs old, thinking that maybe there was a problem. And I read many books on parenting. What I learned was that it boiled down to my parenting style that clashed with her very strong personality. When I changed, she did also. For the better I might add. Here are a few things that I learned. Don't try to reason with her. She is the child and you are the parent. There should never be any negotiation about who is in charge. Never give attention when she is having a fit. Talking to her is a reward. Looking at her is a reward. Pretend she is not there. You will have to have the patience of a saint, because when you stop responding to her tantrums she with increase the fits 10 fold at first. When she realizes that she is no longer getting any attention for her fits, she may even try having accidents in her pants for attention. Simply tell her that if she can't use the big girl potty then she is still a baby and put a diaper back on her. The consistancy is very important. She needs to be able to predict with 100% assurance that A will equal B. There are two books that I would recommend, the first is "Making Children Mind, without losing yours" by Kevin Leman. The other is by Super Nanny. I'm not sure of the title. But personal responcablity is the key. Give her the choice of two things. This will help her feel like she has some control in her life. What ever she choses she is forced to stick with. Example: Two outfits layed out in the morning. What ever one she picks she must keep on all day. If she doesn't want either one than she loses the privalege of chosing, so chose for her. If she throws a fit over your choice than she should be force to stay in her PJ's all day.(Yes even at day care.) Food, she can chose to eat or not eat. But she cannot have any thing else to eat until the next meal. If she complains put the responsability back on her, by saying that she chose not to eat, now maybe she will make better choices at the next meal. Hold her accountable. If she has something to look forward to this will give you some leverage. What I did with my 3 children (who were 1 1/2 years apart) was take them to the playground in the evening.(or McD's in the winter) so they could burn off energy, and so I had something to encourage them with. When you pick her up from day care, and she is having a fit, then she loses the privalige to play. Also my car never moved if one of the kids didn't have their seat belt on, or they were having a fit. I didn't talk to them except to say why the car was pulling over. Then I waited(sometimes a very long time). When the fit was over with , then the car could move.(if you need to stand outside of the car for you own sanity, then do so.) The kids hated this. They didn't like making their stay in the car longer. But I always held them accountable. If you don't get your daughter to respect you and your husband at this stage, then the teenage years will be terrable. The two of you need to be on the same page with each other, so she can't play you against each other. She is a smart cookie. And she is playing the adults in her life like a fiddle. Just remember that everything should come back to bite her in the rear everytime she acts up.(I don't believe in corporal punishment) When it has a negitive effect on her personaly, she will learn that she is in charge of punishing herself. Isn't this the way the real works for us as adults? If I chose not to cook dinner, than who will feed me? If I don't do my laundry will my mommy come and do it for me?(I never had a mother in my childhood). You are preparing her for her future. Hang in there, it does get better. The entire family will benifit from the changes. Give her extra attention when she is being good, sence this is what she really is trying to get with the bad behavior. And make sure she is getting lots of sleep. My daughter is 25 and still gets grouchy, vocal and hyper when tired. Good luck.
