I would like to recommend the Leap Frog Fridge Phonics Magnetic Set. It's a great tool for young children learning the alphabet. My kids loved playing with these magnets when they were 2 and 3 years old. When they were 3 1/2, they received the Leap Frog Word Whammer and it has been an equally enjoyable learning toy that they still use at 4 years old. My children love to spell words and the Word Whammer has been great at assisting them. I also purchased the Leap Frog Letter Factory DVD for my kids when they were 2 1/2 years old. It's a perfect compliment to the refrigerator magnets and helps children learn letter sounds quickly. If you are working on the alphabet or thinking about introducing the alphabet to your children, any of these products would be a great choice.
