In my openion, a mother better take care of a child atleast upto the age of 5 or 6. Just think of a baby, a year old when gets up and looks at a servant's face instead of his/her mother early in the morning. I really feel pitty of those children that do not get mother's care up till the age of 5 or 6. I have seen some parents who leave their children in baby care, early in the morning when they are asleep. When they get up they see just stranger's, not parents. Really that scene touched me a lot.
