If you do not care if they pull their Child I would tel them flat that you did not like it and then maybe write down on a daily basis what the child ate how much and the times of the meals and the snacks. Give this to them on a daily basis and this shoudl shut them up and if not then I would tell them you do not derserve this kind of treatment and that they can find alternative childcare. parents do not realize how difficult it is to take care of children and they should be thankful when they find a good child care provider. I have been there times in the past and just came out and told the parents how I felt and that they could take their child elsewhere etc.. Where there is on family there are 2 more families looking for childcare.
