People have multiple personalities and a lot of it has to do whit what kind of childhood we had. I know I'm my dais it was said that you have to let your kids cry and they will calm them selfs down. For this, I was listening to a podcast where I found out that that isn't true. When kids are crying they will come them self down but they will get a message that they are not important.  More you can listen in the podcast.

Hope you find this useful.
