Yea, been there done that. Six months is a difficult time to nurse because of all the distractions. I have two suggestions. First, try to nurse in the bedroom on the bed lying down on your side, no one in the room, no tv or radios, complete silence. Instruct the sibling, it feeding time and to stay out (have something fun for him to do while you nurse). You will be able to relax, and the baby will have no distractions only you to enjoy. Second, if pumping is easy for you save that liquid gold and give the baby a bottle for feeding time. In time this will all pass. When the next growth spurt starts, that baby will be nursing more. I know its hard, just hang in there, and keep on with the breastfeeding. Good Luck!
