I wanted to add my thoughts and encouragements. My son is 7 months now and nurses wonderfully. However, he didn't start nursing until he was 6 weeks. During that time I pumped and did okay. Each time he was hungry I would try and feed him for a few minutes and he would get really upset. Then we would give him the bottle of expressed milk. Eventually he figured out what he was supposed to be doing. I don't think it's too late for your wife. Just keep trying to feed breastfeed him and keep pumping in the meantime. It the most frustrating time but the rewards are worth it.
