I would stick to your guns on the fees for sure - good habits are established early on in the relationship if you allow 'excuses' to be given to get off from not doing something in your contract - well the excuses just get more creative as the relationship grows

With the sunscreen I would just say I empathize that is sucks that he got burnt however it is the CLIENTS job to ensure they have read and are familiar with the policies - dad needs to make sure he has READ the handbook as the policy clearly indicates it is the PARENT responsibility to sunscreen them prior to arrival and how were you to know he had not been?.

I actually have a sunscreen consent form that they have to SIGN specifically cause I do not want to mess with being blamed for a 'burn' .... outlines if they are supplying sunscreen or if they want to consent to be a part of my $10 a year sunscreen program and I supply Badger for the 'face/shoulders' and Green Beaver for the rest of the body, it also outlines that if they arrive after X time frame the parent has to apply it at home so it has time to soak in at least 30 minutes prior to outdoor time, that I will apply it again 30 minutes before afternoon outdoor time as well as after water play or vigorous sweating. I also have a section for them to opt NOT to use sunscreen unless we are in bathing suits cause some people feel that a hat and clothes are enough to protect them from burns and some sun is 'good' for them so they do not want sunscreen used unnecessarily.

I will admit that if a client arrives 'late' I tend to ASK if they remembered and will apply it again if they did not just cause i do not want a child to suffer cause their parent dropped the ball ... however I remind them 'hope it has time to soak in cause we are heading out now' so if they DO burn it was because they dropped the ball not me
