I let my 13 month old use these. He absolutly loved them! DO NOT LEAVE ALONE! They aren't easily breakable but after a toddler drops on the floor a few times it results in breaking. My 13 month old was able to hold them easily. I really liked how the top part is easier to hold and about the size of a golf ball. It even has a hole in the top where he can put his finger in and move it around that way. This is a great product and would be a great gift, as long as you don't leave a child unattended !#RankBoosterReview #Sponsored #Dmeixs
