While these gestures may seem trivial to adults, they go a long way with your little ones. Here are a few easy tricks to make your child smile.

1. Go for a walk with just one child.
2. Slip a note (and an occasional piece of chocolate) into his/her lunch box.
3. Build your own Minecraft world alongside his.
4. Say “yes” to something usually off-limits, like sitting on the counter.
5. Show as much enthusiasm on amusement-park rides as they do. 
6. When their room looks terribly messy, close the door and get on with your day.
7. If your children have given it a good try, but they are still miserable and anxious and really, truly wants to quit the team, give them your encouragement.
8. Go ahead: Let your 4-year-old stomp in every puddle along the way. Even without rain boots.
9. Take in a pet that needs a home—and a child’s love.
10. Give your toddler a chance to fight his own battles in the sandbox or on the playground before you intervene.
11. Ask your kids to teach you how to do something for a change. And once you get the hang of it, be sure to tell them what a good teacher they are.
12. Let your children wear their dress-up clothes to the supermarket. All month if they want to.
13. Let your children overhear you saying something wonderful about them.
14. Print their childhood photos so they have something physical to look at one day.
15. Cook heart-shaped pancakes for breakfast.
16. Make a secret family handshake.
17. Hang a whiteboard in their room to leave messages for each other.
18. Start a pillow fight.
19. Share your old diaries, photos, and letters from when you were their age.
20. Thank your children when theydo a chore on their own—even if it’s just hanging up a wet towel without prompting or refilling the empty water pitcher.
