Also, we've had to give him more in his bottle at night. He just couldn't last with two ounces per feeding so we made three-ounce bottles last night. That helped a lot. We fed him at 10:30 p.m. and then he woke up at 1:30 a.m., 5:00 a.m. and 6:30 a.m.! That's much better than waking up every two hours like he had been doing!
