I was in the grocery store and this toddler was sitting in the cart SCREAMING like he was in pain. His mom was yelling at him to be quiet. This was at the deli. I look at the kid and see his leg is being pinched in the seat. I pointed it out to the mom and she freed him but just left him in the cart crying and didn't even look at his leg which you could see had a huge red mark. Poor kid.
Sometimes kids scream for no reason and I get that. But at least make sure it is for nothing.
