What is your pre schooler first hobby?

My nephew was about 3 years old when he started to pick up crayons and draw all over everything! It was charming, at first. But then he started drawing all over my cousin's (his mom) room's wallpaper! That's when we started buying him bigger coloring books because it seems like he needed a bigger canvas. He's turning 9 now and he still loves coloring but he's fallen in love with reading as well! :)
