Walking into lego camp, the first thing the counselors did was ask my son to spritz his hands with a hand sanitizer because there are campers with food allergies and we have to be careful. No doubt – I don’t want to risk any child’s health. That said, I asked that my son be told to wash his hands in the bathroom to prevent contamination because santizers are bad for you. Obviously – if there is no running water, by all means, use an anti-bacterial gel or foam (but if their hands dry within 10-15 seconds...you need to use more).
But for allergies – that’s not going to help
