I second GM5's post about potty accidents...my DS7 when he was between 4-6 would have accidents because he said he didn't want to stop what he was doing....they get so involved in whatever it is they were doing that they don't want to miss out on anything. Or they just get so focused on what they are doing that they ignore the potty signs until it is too late to make it. I was really worried that the other kids would start to make fun of him for having the potty accidents....he has outgrown this now that he is 7 but we do every once in awhile have to watch. If we are out doing something really cool or if he is massively focused on something, I will make some reminders about a bathroom break....hang in there smile
