My 3 yr old Twins love this DVD. They enjoy the entire Leap Frog DVD Series, but "Let's Go to School" got them interested in attending pre-school, and gave them something somewhat educational. They really enjoy watching "Talking Word Factory" and "Letter Factory" are their favorites. They started watching it a 2.5 yrs of age and they both know what sounds each letter makes, recite the alphabet, and can spell their names. They like "Math Adventure to the Moon" too, and although it may be better for 4+, they are great with counting the numbers with the DVD. They are also terrific for longer car trips, they watch one after the other and it keeps them interested.
