Despite the fact I am not the ideal age range for this product, I still loved it and found it a great way to relax and have some fun in this tough times! My only issue that the felt remained bent out of the box and I'm worried the teeth won't remain sticking on it for long.

My 5 year old grandson has been into dinosaurs seems like forever. He was over joyed with this "head". I was the first thing he showed me the last time I went to see him. Infact he has loved all the crates he has received. The thing I like most about KiwiCo. the children have fun and don't really know they are learning.

My daughter was super excited about this dinosaur. However, it constantly slide down on her head and she can’t see.
