I have been looking for a program to teach my children polish. I have tried tons. My kids ages 3 and 5, love these videos. They watch one everyday. It has only been about a month,but they already know so much. My inlaws who speak polish said they are learning so fast and have excellent pronunciation. This is the best program ever. These videos make it so easy to pick up the language. My kid don't even realize that it is learning program. I love it! I wish they had a more difficult version after they master these videos that they can go on to.
