Mine when 4 yrs old or so grabbed something at the checkout counter when with the Mrs.
The wife didn’t see it until they got home. She ended up taking the little one back to the store and making the little one tell the manager what she had done and returned the trinket.
Never had a problem with her ever taking something that wasn’t hers. She now has two Masters and teaches both high School and College.
One of my four did also. Took her right back to the store and made her pay for it. My Mom did the same for me when I was little.
The last thing I’d do is drag my 7 or 17 year old down to the police station to teach her a lesson.
