Help choosing a kids tablet

Hi. I’m looking for a tablet for my 2 year old daughter to take on holiday and for on the plane. I’m looking for something reasonably priced with enough memory to download a few cartoons and apps to keep her entertained on the flight, etc. I was looking at the kindle fire? Is this a good choice? Also, what kind of GB should I be looking for? I really Don’t have a clue so any advice would be much appreciated. Obviously as she just young I don’t want an i-pad or anything incase she brakes it although I will be getting a protective case for whatever I do get her. Has anyone used the kids kindle? Does this already have cartoons, etc installed. I look forward to hearing your advice.
