I think as long as the carers are ok with it it should be fine. It's their job to care for the children and if that means changing clothes so be it. When I had trouble getting DS to clean his teeth, they encouraged me to bring his toothbrush in and they would help him there. I would always try at home but sometimes time constraints and unco-operative toddlers meant it was either take it in or go without cleaning his teeth. Having that option is such a sanity saver even if you only use it occassionally. All of the carers at our daycare are incredibly helpful and love the kids to bits. They are always willing to do whatever is needed for each individual child.

Good luck Fiona
