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

Great project for father and son to complete

It’s a really cool dinosaur head, and the instructions are very straight forward. I did this with a nearly 5 year old so I expected to do quite a bit. We took a break to keep him interested and ultimately it’s a fun item but a bit more costly if your child doesn’t use it much.
