My 4 year old daughter loves dinosaurs. We just got her a big girl bed and, of course, she wanted dinosaur sheets. I looked everywhere, but couldn't find sheets that didn't scream "boy's room". She didn't like any of those, anyway. This sheet set is awesome. It's very colorful and we noticed that some of the dinosaur types are even in different colors (it's fun to think of them as boys and girls). The flannel is very soft and not too heavy. I was glad I could put them on her bed right away, even though it's very warm here. My daughter loves them! I wish I could find a matching comforter, but I'm at least going to buy a second set of sheets. Now she wants me to find the purple dinosaur toy in the picture, too, lol!
