Review on Wooden Puzzles Kids Ages 3 5 by Aquarium Lanter

The puzzles are solid and well made. The problem arises from unusual shapes and the lack of traditional corners or straight edges. I encourage you to watch the video. No pictures of assembled puzzles are included. I honestly don't understand. An older child can challenge themselves without looking at a picture, but why upset a younger child? My 3 year old grandchildren couldn't do it on their own and even the adults struggled. I'll take pictures of the puzzles next time, that will help. Kids grow up fast and I know that one day it will be easy and fun for them.
