A 'Parenting Expert' has apparently come up with a 'new hack' to teach your child to say Thank you. It involves handing something over to your child and lightly holding onto the item until the child says Thank you. You then release. The article says this is a new technique that nobody knows about... My son is 18 and this was something I would do automatically when he was young to remind him to say Thank you. Only having to hold the item for a couple of seconds. Am i wrong in thinking that most parents do this automatically and it's not a new idea?
