Thich Nhat Hanh said this quote
“ Please don't wait until the doctors tell you that you are going to have a baby to begin to take care of it. It is already there. Whatever you are, whatever you do, your baby will get it. Anything you eat, any worries that are on your mind will be for him or her. Can you tell me that you cannot smile? Think of the baby, and smile for him, for her, for the future generations. Please don't tell me that a smile and your sorrow just don't go together. It's your sorrow, but what about your baby? It's not his sorrow, its not her sorrow. ”
