If you triple click the home button on your iPad mini, it will give you the option of selecting the Guided Access option. Once you select that, you will see the options button and you can select what you will like to disable while your child has it. Once he is finished using the iPad, you can triple click the home button again and select the option to end Guided Access again. This has saved me from so many meltdowns with my child. I hope this is beneficial to you.
