Hello!  I am the parent of one 5 year old boy.  Do you have any children?
No, but I like to think that I know a good deal about the process of promoting and supporting the development of a child.
How much experience do you have with children? 
I know a lot of people who have kids, so a decent amount. Though of course the most common caretaker of children are the biological parents and not someone like me.
I grew up the oldest child of 3 kids and am a teacher, so lots of experience with kids!  It definitely is rewarding and requires a lot of patience
It really is, but parenting isn't the only thing that impacts child development. Governments and society also play a role in that as well.
