One of my first activities I did, was cutting a box and make a car out of it. My daughter helped me decorate it of course. The only thing you really need is a box big enough so your child can sits in it, some tape, colors and imagination!
She felt very proud of her car, that she made by herself! And the best, she could carry it everywhere!
She could color on it, too!!
She loved here car so much, she even used it as a table, to read a book, to eat or just relax in it.
