Valerie, I do agree with you that religion should be taught at home. I do know a lady who runs a very Christian daycare and she attracts her clients because of that, but we don't talk about it at my daycare either. It's exactly as you described with the fun kiddie version of holidays.

However, I don't think I'd put it in my contract or on my website. But I check with families when they are signing the contract to ask them if they are alright with us celebrating all the holidays and birthdays so that I'm respectful of the parent's wishes.
