You aren't letting the child down, her parents are. By accepting the child into your daycare without a pull up which she undoubtedly needs, and having done this repeatedly, there is no incentive for the parents to meet your request. If you absolutely want to try for the child's sake,you need to get in touch with this family over the weekend. Not text or email, a phone call where you can exchange dialogue. Do not ask ther parents to do anything, that implies a choice, tell them that Monday morning she must arrive in a pull up and with additional pull ups. Make it very clear to them that should this not happen on Monday, or any other day for that matter, she will be turned away. If they try to pull a fast one and drop her off and say "oh I forgot. I'll nip and get them now and be back in 5" I call BS! Do not allow them to do that with their track record. Chances are they wont bring them and you'll have allowed them to take control of the situation by not following your rules. Once she is back in pull ups permanently and consistently, you will be able to work on her other issues easier without the whole toileting obstacles. This is the only chance you have of gaining back control and calling the shots with this family and with your business. Should they choice to try and disrespect you again by not doing as they are told, essentially, then make absolutely sure you give them notice. If you do not back up what you say, then it won't be at all surprising should they continue to not give a toss what you want and keep marching to the beat of their own drum. Rest assured though, you are going above and beyond in your role as caregiver to this child and no matter how hard you work, if they refuse to get on board 100%, you are fighting a losing battle. Shame on them!
