Hi all. I have a problem my in laws have made my toddler mastikhor. They dont teach him anything n when im sitting with him to teach him , he doesnt sit ( coz all he wants is his dada to do masti)

When i was at my moms place he would color,play independently for 15-20mins min, read books, solve puzzles etc but after coming back to in laws house he doesn't coz they have inclined him towards masti.
What should i do plz suggest
