I want to get my 20 month old his own Ipad, Tablet, or Kindle for Christmas. Which one would you get?

Also, because I have no idea - what are your kids favorite apps?

I know having kids play with an Ipad, Tablet, of Kindle is controversial, but my husband works long hours and travels and this mom needs LO to be entertained for a few minutes to get dinner on the table. Hoping an Ipad, Tablet, or Kindle does the trick.
