Certainly! Heres the translation of your message:

"Choose missions and rewards that your child needs for their habits together :)
Through daily habit mission completion, accumulate experiences of success and record them.
Through accumulated experiences of success, you can move towards bigger achievements.

Here are some good points for rewards:

A reward that can be received every day when all daily missions are completed - If the reward period is too long, the child may lose interest.
Rewards that are only given for mission completion - If rewards are given for things other than mission completion, the meaning of the reward diminishes.
Rewards that your child can consistently enjoy."
