ds gets really absorbed in playing with a toy or in sand pit for example and if I have to stop him ie time to go out or for lunch he has a melt down, I know its because he's enjoying what he's doing and is frustrated because he doesn't want to stop but I don't know how to tell him we're about to do something else and let him wind down from what he's doing, when we had this trouble at bath time we resolved it quickly by telling him bath time was over and pulling the plug when there is no water he knows its finished, obviously telling him '5 mins before we go out' will have no meaning... any advice? (I'm 28 wks pg and its getting frustrating and tiring!)
