What's the best part of having children?
I am not sure if I can answer to what is the best, as I love many facets of having kids.  I have three children and they are each 5 years apart.  Each child has their own personality and traits however they all share their love of laughter, affection, dance, singing and all are clever.  I love having a little hand in mine as we cross the street.  Seeing my child's eyes light up when I am watching them do something they love brings more joy to my heart than I can explain.  There is also no way to ever fully explain the feeling of love and happiness when I get a nice big hug, especially after a long day.  I also learn a lot from having children like being more patient, curious, empathetic and when needed decisive and firm.  There is not one thing I love best, but all the things!
