juggling their works & babysitting chores, sometimes little kids just ended up in nurseries or some nannies:( Time is valuable for me, once it is lost, especially concerning the kids, it could never turn back the time.
The feeding, the changing of diapers, taking them to beds, teaching & laughing with them, with yourself, I guess money cannot buy them.
As a mother, you always cherish their baby pictures when they all grew-up & gone away.
