The Leap Frog Fridge Phonic Magnetic set is a great thing to have in the kitchen. I bought it to keep my daughter occupied when I was cooking dinner, and it worked.
This set consists of a magnetic letter reader that sticks onto the fridge. 26 magnetic letters come with the set, and fit into the letter reader. When your child fits the letter into the reader and presses on the letter, a song begins that says the name of the letter as well as what sound it makes. There is also a button that you can push to listen to the alphabet song. There are two volume settings, which is nice.
The magnetic letters are large and easy for little hands to handle. They are different colors (the vowels are red), so this set can also help children learn their colors.
For little children, the letters are sometimes difficult to fit into the letter reader. They have to go in upright, which is easy for an older child to do that knows what letters look like. But determining which way is up is a little difficult for a 22 month old.
