I love these flash cards for my son, even though it says 4+ & he's only two. He doesn't talk much but I'll lay them all out and tell him to find different animals and he knows them all. It's really helped expand his knowledge of animals. I only wish they were made for younger children and were a little thicker because when he gets excited he bends them. But they will be great as he grows as they have facts about the different animals on the reverse side.
