This is the perfect kit for two year olds! Others curriculums I have tried have been too easy (and boring ) for my older toddlers and others too hard. Things I like about the Little Learning Box: the number focus is on 1-5, the books have just the right amount of text, the creative projects don't require cutting, the letter focus is just right, and the instructional guide is presented in a logical and easy to follow format. What I would like to see more of: gross motor activities and dramatic play. Overall I highly recommend this kit for ages 2-3.5 years and for mixed age programs. It is a real curriculum that doesn't rely on fancy parent pleasing fluff.
