You can anticipate their hunger, right? Instead of waiting for them to notice it themselves, bring food to them, where they are playing. Or prepare something that smells so good it draws them into the kitchen. If you need to be somewhere in the morning, then help your children feel ready for bed earlier in the evening. If they are old enough, then you can just discuss this with them the day before and let them figure out how much sleep they need/want. If they are younger, though, you’ll probably need to help them feel ready for sleep (if it’s earlier than they usually fall asleep). Read books or play quiet games with them. Draw up a warm bath and add colors, scents (lavender is very relaxing) and a few water-friendly toys and then let them relax. If your child needs more physical movement before s/he can be ready for restful activities, then be sure to do that first (jump on a trampoline, set up an obstacle course, time them running and jumping with a stopwatch, etc..). Once they have released their physical energy, then they might be more receptive to quieter activities. Basically, unschooling isn’t about letting your kids figure things out on their own. Be their partner and help them when you can anticipate a need!
