hmm. interesting about using please. I guess I didn't realize what the true meaning of the word meant. I wonder why it's considered manners/ polite then? If you go to a restaurant and ask the water for "a refill please" you expect it to be done not just if they would like to... so why don't we just leave out please?
oh well
It does make sense that toddlers wouldn't know what to do with the word when given a command, it's just an extra word that doesn't mean anything to them really. I think of someone consistently used it with their commands the child may begin to associate it with the command and not optional. But then what happens when it is optional , if you do use it? Would they get confused? Maybe the key is just being consistent with whatever approach you use.
