I only have one with a paci right now and he's 14 months old. I have to say that I kinda like it because he tends not to put every toy in his mouth
I can control how much the child gets it here, but cannot and wouldn't try to tell the parent what to do on their own time. I prefer to keep the paci's in their bed if they are still using them. That way they can't share them with others and I don't have to look for them or clean them. No big deal. I really don't think it's for me to tell the parent what to do in their own home, just like I wouldn't put up with them telling me what to do in mine.
