I didn't want to brag about all of the things my son has learned from the IPad. It is so much more than just states, capitals, and some countries. He knows every country in the world, including Island Nations. He knows how to spell every state in the USA. He can also spell nearly very country in the world. Countries like Indonesia, Pakistan, Afghanistan. He knows nearly all of the world capitals. His geography goes way beyond states and capitals. It wasn't about me trying to say how much my 3year knows. It was more about me saying how his IPad has helped him.
It has also taught him many other things than geography. The IPad has helped teach him to read, write, count. There is even an app to help him go to the potty. The list goes on and on. If you can think of a traditional subject, there is an app for that. He can print nearly as good as my older children. He can read better than my 5 year old, and she's a good reader. The only thing different in the upbringing of my children is the Ipad. So in my case I think it has been a huge advantage for my youngest. I know there are a lot of people who do not want to embrace technology, but it can be a huge help. It's like anything in life, moderation. I'm not saying you should have your child on an IPad all day. However, it can be a huge aid in the development of young children.
