My dd is 3 1/2. She started preschool a couple days ago, but she has been at the same place since May in their daycare. Everyday she tells me she doesn't want to go to school and that it is "yucky." I've asked the teachers and they say she does great and when I pick her up she is playing and doesn't want to leave. I've even hung out there for a hour one day and she seems really good there, but the minute we get home and all the next morning she says she doesn't want to go anymore. Is this normal? Is it just a toddler thing or should I be worried.
