I give a weekly receipt with each payment using a receipt book I get at Walmart - like how it is worderd which gives me a duplicate copy. I also give a one page monthly summary for tax time in January for the preceeding year.

Vaccinations are up to the parents but I reserve the right to exclude a child during an outbreak of a disease they are not vaccinated against since they are more vulnerable to catching it and bringing it into daycare as most vaccinations reduce the severity of a disease not prevent it.
