Don\'t feed formula if you have enough milk. Some people don\'t even have enough milk to feed the baby. My baby was still yellow when he was 1.5 month old. He needed to stay in the hospital for a night. I cry but I didn\'t give up feeding him my milk. I pump and pump when he stay at the hospital. I know it\'s the best for him and that\'s all I can do. If you pump your milk, at least you know how much your baby drinks and your family can help you feeding your baby too. That\'s how I became pumping mom. Now my little boy is 2 months old. He\'s way less yellow. Don\'t give up. We are here for you.
