Well, we here at Woman and Mom have a small but simple idea that you can involve your child(ren) once you step foot into the store.
While you are on your way to the grocery store. Let your child(ren) know that they are going to become mommies little helper once you get to the grocery store.
Get your child(ren) excited. Remember to try to say it with a lot of enthusiasm in your voice...
Once you get to the store; have your child(ren) be in charge of the grocery list. Make them feel important; like they are holding the golden ticket.
Depending on their age; while holding on to the grocery list aka golden ticket. Have your child(ren) help you pick out the items that are on the list, and put it in the cart.
Of course if you have more than one child. You can create different job duties that each one will have. One could be in charge of the grocery list; while the other is putting the items from the list in the cart etc.
This will hopefully help to keep your child(ren) out of Mischief; while at the grocery store.
Make it Fun Happy Shopping...
