Thank you for your comment and for the congratulations :D

And with regard to placing chores at home, it seems perfect to me, as my daughter still doesn't know how to count, (only until the 10th) what we do is do something similar, only that the benefit is the snack.

It just occurred to me when I write this, perhaps in the future a kind of investment system will not be a bad idea; "You give me two of the cookies you have saved and in 3 days I will give you 3 cookies". It's a very crazy idea, although it could work hahaha
