Read articles on the magazine The Mother and you will calm down and be at peace. By nature, a child breastfeed for four or five years. She needs it. If you did it the natural way she would still be breastfeeding. Don't be embarrassed by proud of yourself and let her suck or she will end up resenting you, biting her nails, or later on smoking. She is fine and she must have the bottle until she doesn't need it. She needs it.
