They just need to put it one way, and leave it. DST saves energy? Keep it that way, you'll save all year. Kids going to school or coming home from school in the dark, guess what, it's winter in the northern hemisphere, and the further north you go the longer it's dark. Learn.
The trick with small kids is to gradually change their schedule, starting a few days prior to the time change. I've found that about 15 minutes a day over 4 days works pretty well, unless they're really sensitive to the time, in which case do it over 6 days at 10 mins/day. They won't notice a bit - unless you have a TV routine based on some network.
