I have two set -lrb- over 4 year -rrb- , and these be awesome ! of course , any suction bowl do not really stay down . you kid will figure out how to get they off ! however , these be still my favorite bowl . they be incredibly stable and sturdy , they travel well -lrb- for snack , even wet one -rrb- , and they last age . only wish I could afford 50 more , and that there be a easy way to attach the lid . I use they for a 5 and 1 year old , and have send they to work with dad , too , for salad dress .
