Anonymous wrote:12 hours of sleep???! Let kid stay up later into the evening. You are expecting this kid to sleep all the time. Tell your kids they need to entertain themselves in their own rooms until the sun is all the way up (7-8). You can read a book in bed, etc. Just be quiet enough that everyone else can get more sleep.
But putting this kid to bed at 8:30-9 will help a lot. Also, take this kid outside to run around at a playground and make your kid start walking more often. Stop using the stroller so much. Your kid will sleep like a brick once you start making him or her walk.
While I agree with this in general, not all kids will “sleep like a brick” with enough exercise. Kids are different. I’ve had parents tell me my kid “needs more exercise”, and often they have kids who will play hard at the playground for two hours and then pass out the minute they go to bed. But my kid will run around for 20 minutes at the playground, then spend 40 minutes playing some pretend game with grass and sand while sitting quietly. And at bedtime she will take longer to fall asleep because her brain “feels busy.” She just has a different energy and speed, and there’s no point in trying to turn her into a “play hard, sleep like a brick” kid. Different kids are different.
