July nanny for 3

We have three kiddos that are very close in age (7, 5, 4). They love playing together! Our oldest has type one diabetes, which we are happy to train anyone who is unfamiliar how to manage it (all using technology- no shots). We are looking for someone to help our kiddos have some simple summer fun! Care would be sometimes for all 3, some times 1-2 depending on the day and schedule. We have a beach, bikes, sprinklers, and the kids enjoy the nearby playgrounds and library. We are looking for care for the month of July.
