Ok so I have just changed the 6TH pooey nappy of my DS, 2.7. For the second night in a row, it's as if he has saved up all his poo throughout the day, and then proceeds to do them all, call me upstairs to change him then do another, and another, and another, aaargh! I know it's a game now that he's done it again tonight, but equally I don't want him going to sleep in a soiled nappy - last night I changed one in his sleep on my way to bed as I didn't believe he could have done a fourth poo and was just playing a game. What is the best approach to this?
