No, I don't like to wake the children. I think they should sleep as long as they need and wake naturally. My little ones all sleep at least 2 hours in the same room and the new baby who wears cloth diapers wakes up as soon as he poops, between 1-2 hours every day so he's in the other room. I have one child picked up at 3:30 every day so I get them in bed by 12:30 so they are awake by 3ish for potty/diapers & snack. Sometimes if they sleep a long time I'll wake the early pickup child only and let the others sleep.
