Wondering if anyone has a little Inventor on thier hands??

My 4yr old has been "Inventing" things since she was 2yrs old

at 2yrs she took bars from her broken babydoll highchair and atached them to her babydoll stroller so she could set the baby carseat into the stroller

she one time made a frissbee out of paper (shes never seen a frissbee we dont own one) and she called it "The Disc-O-Ball (because it was a disc shaped ball)and threw it like a frissbee

more recently she used the bicycles to build a car and got upset when she realized that because of the way she connected them together it wouldnt actually move

most of the time its just little things and almost always something thats been invented already that shes never seen (like a sling shot or a top)she often builds things and is upset because they dont work the way she hoped
