I too believe in teaching children to respect their environment and I have an amazing group of children year after year who are kind, gentle and respectful ... unlike the Daycare Whisper we manage to do that with only 3 rules in the playroom!
Is it safe? Is it respectful? Is it productive to meeting a learning goal? If the answer is YES than do it and if the answer is NO than you don't do it .... easy peasy lemon squeezy to remember those rules and apply them anywhere where we go!
