Our son loves the stacking boxes with the motives. Beautifully printed plain paper on heavy card stock, which is also short "Sabberattacken" survives. Only to bite one may not leave it to loved ones. Our son was beginning about 6 months old and enjoys it now already almost a year again. One can show much, explain, promote motor skills, introduce colors and numbers slowly. Have now also given away a - am very satisfied.
