Yes thank you. My friend’s wife does that very well, it’s impressive. She waits for her son to stop crying and then she gives him what he wants after he asks for it using his words. I don’t like saying this but it’s kind of like teaching a dog. You want to reward the good behaviors and ignore the bad or block the bad behaviors. My psych professor when I was doing my undergrad told me that lol. Kids are kind of blank slates. They don’t know what works and what doesn’t so they try different things. Crying tugs on our heartstrings so it gets the job done most of the time. But why is it that some children cry while others scream? Why is that some kids will hit themselves on the head to get what they want? The kid that hits himself learned that this gets me what I want because crying and screaming doesn’t work anymore. But these are all learned behaviors reinforced by parents is my point.
