I bought this for my kids to play with at Grandma’s and from 0-60 have enjoyed this toy. The kids can practice colors as well as stacking.
I have mixed feelings about these! In the beginning, it was very difficult to get the largest nesting doll to open (in fact my husband had to do it several times). However, now that they have been played with a few months, it is much easier, and my 2 year old really likes them. Note, though, that the two smallest are choking hazards!
