I have not breast fed my first daughter since she was 12 months. Would it be a bad idea or crazy to want to start breast feeding her again? I feel weird for asking but I'm concerned about her health and I feel like breastfeeding would be good for her. Can you retrain a 3 year old to breast feed? I'm also breast feeding my 5 month old. Is this strange to want to breast feed her after all this time?
