Scott & White offers these tips:
Injuries from shopping carts are much more common than expected. Each year approximately 23,000 children are treated for injuries sustained in falls from carts.
· Most injuries occur when the child falls from the cart or the cart tips over.
· If your child must ride in the cart, make sure the safety belt is fastened.
· Do not let your child stand in the cart.
· Do not place an infant carrier on top of the shopping cart unless it is designed as part of the cart.
· Do not allow your child to climb in or out of the cart.
· Do not allow your child to ride on the side of the cart.
I think I personally have allowed or seen my children do all of these things. How is it they have not cracked their heads open yet?
