Hi A.
I can understand the feeling you must be having, your poor little girl. I know that is not how I would want my child to spent their day at preschool. That does not sound like a positive learning enviroment. It sounds as if your daughter is a very smart little girl and has probably told you pretty close to what the teacher said and did. That to me sounds like way to much for a 3yr old to make up. I have to say though I have so much respect for you in that you are willing to go in a talk to the director. I think I would have that gut feeling of kicking the teachers rear and yanking my child out. You seem to be handeling very well.
I myself am in child care and I always ask parents to please talk to me as I will them about things their children say. Now in a case like yours I think that is a lot for a child to makeup and if a child said something like that about me I would close my doors. But you must be happy w/ the preschool, just not the teacher. I think it is wise talk to the school, the school may be very good, they just hired a very bad teacher. It will save your daughter a lot of adjustment if the school has a chance to correct the problem and put a new teacher in her class. I think there is nothing wrong w/ looking arround for another school in the event the school does not correct the problem, or correct it quick enough it is always good to have a plan b.
I really do respect the fact you are taking the time to think this through to do what is in the best interest of everyone. I know as parents we want to jump so quick to be our childs hero and fix things and some thimes we make things worse or harder on the child, like switching her school. I hate what that teacher did to her w/ the orange, not only did it embaress her but she could have chocked. I think if you and your daughter are happy w/ the school except for her teacher, why should the teacher get to stay and your daughter have to make all the changes and it be even harder for her. She is the innocent one, I say make it harder for the teacher, remove her!
As far as the wiping thing, from a parent point of view I would rather help my child wipe so they are cleaned well. From a child care provider point of view I always let my children know that use the potty to let me know if they need help. I do not go in the bathroom w/ them or watch them. I will check on them if several minutes have passed, I even ask if they need help. If a child does not ask for help or says no when I offer I do not push the issue. Once a child is trained (for a while) the issue of helping can't be pushed by child care providers, I feel once a child has been trained for a long while and successful in all areas except the wiping after pooping, the child can say yes or no to help in that area of their body and it needs to be respected. I don't know how the providers are at her school, they may not even offer any help. I have to say there are times I have to go above the childs request and help them if I notice by smell it may not all be cleaned up, or if I notice it happens to be a messy one I just go in and shut the door and explain that I need to help them so thy don't get a sore bottom. I have never had a child freak out and say no, I guess if I did I would not touch them. I would probably call mom or dad to come take care of it. I just feel as child care providers we have to be careful and respect the childs body and rights. And again things can be said at home that could raise a parents eyebrows. If your daughter came home and said miss so and so touched my bottem today and you asked if it was because she pooped and she said no, then what? Maybe miss so and so just wanted to do a double check before the child went home, or maybe she thought she pooped, or maybe the child did poop and the child does not remeber what happend 6hrs ago. It can just lead to lots of qustions, raised eyebrows and so its best for providers to offer help and give it when asked for. Since we are not the childs parent we can't risk crossing that line.
I did not mean to go into so much about the wiping thing. That is a tough issue on both sides of the coin. Talk to the school maybe about her bringing her own flushable wipes. If she does not want to ask for help or can't get help maybe she can bring the wipes in w/ her and she will not have as many rash problems. I wish I had a better answer on that one.
I do wish you all the best and please keep us posted on how it all works out.
