Childproof my IPad and now my son is mad

My one year old is so found of my IPad and sometimes I just really run out of energy so I let him play with it.

Today I found out how to childproof it and now it only stays with the Sesame Street app. My son was happy at first and now he is so mad 😂

He keeps pressing the home bottom and nothing happen, he kept giving me the IPad and asked me to fix it and I was like ╮(╯▽╰)╭

It is kind of fun.
