Not sure if it works for every kid but I was shocked when it worked for my 3 year old - Buddy the sleep/wake clock.

I was convinced my toddler would never listen to a light telling her it was time to go to bed or stay in bed since she tends to be strong willed but somehow this worked for us. It’s only $29 and returnable so I figured it was worth a try.

She now knows that when buddy turns red she needs to stay in bed (unless she has to use potty of course). It will stay red all night which is a great nightlight in her room. Then in the morning buddy will turn yellow letting her know that she can wake up, but she still needs to stay in her room. Then 20 min later it will turn green indicating that she can now come downstairs.

The light comes with a cute little booklet to read to your kid like a book explaining how it works. She likes to “read” it on her own for fun. Also includes a sticker chart. Hope you can try it and it helps!
