I don't have a child of my own but I salute every parent who devote time for the right upbringing of their child. My sister (who is a damn good ophthalmologist), gave up her professional career when she had her first son. She devoted all her time to him. She had a plan to go back to work when he grows up the nature had intended something else, a daughter came along 5 years later. So now, she is a full time mom and she is enjoying it. Devotion.
I'm so glad your sister had that option! I am envious of women who can afford to stay home with their children.
