I do take photographs of my day care kids for craft purposes, as gifts for their parents, and sometimes I will photograph an injury as well (Ex: if the child fell and it produced a bruise). I do not put photos of my day care kids on the internet or share those photos publicly. I am very uneasy having photos of my own children online or shared publicly so I just don't do it. That's just my personal opinion. If you decide to put photos of your dck's "out there" then for sure get signed consent from all parents and be sure that they understand the potential risks of having their children's photos displayed online, etc. I have my policy on photographs in my contract. I have never had a parent hesitate to sign permission to take photos but I think that is largely because they know that they are confined to the two parties (me and the family).
