I use Green Beaver or Badger brand on my kids...it is expensive though! But it is all natural. I would not use a bug repellent on children...it had deet in it which is pretty toxic. If you do want to use a repellent, I would make sure you get the parents' permission as I know I would be furious if my daycare provider put it on my kids without me knowing (when my kids were in daycare). I have the parents provide the sunscreen because I don't want anyone having a reaction (it happened with a child this week, but it was his own sunscreen) and me being blamed. Also, I couldn't buy the cheap stuff and I can't afford to buy the good stuff for them all!
