Started this program a few weeks after my sons 3rd bday. He had a keen interest in letters and their sounds already. After 4 months of very slowly going through the lessons (sometimes we do one a day and sometimes we get through one lesson a week) he is now really understanding how to put sounds together to make words!! I think this program is awesome and I am so happy I purchased it. It’s simple and fun, and he looooooves the songs. We sing through them ALL every time we have a lesson. It’s very cute. I’m sure if I would have pushed harder we would be done, but I’m not trying to rush the little guy. Thanks a lot! We love learning how to read!
