It’s definitely a very motivating curriculum and the key is to make it as fun as possible. My 4 year old likes it a lot. The songs get so repetitive though. You can’t really differentiate which letter it is by the melody since they’re they same 3 circulating. My son knows the sounds, but still has a hard time putting the sounds together as a word. So we’re still working on it. Good program all together though. It also takes us longer than 15 minutes a day especially with review, coloring and putting words together. I’d recommend it to anyone wanting to give their little one a head start
