T.C.
I wouldn't worry yet. I don't think my son was making much eye contact at that age, but my daughter was. I think each baby is different. My son's eyes still crossed at that age and even until two months (maybe even longer!) and I began wondering if he was going to have issues. Turns out he's just fine and he makes great eye contact now. I think some babies take longer than others for whatever reason. I wonder if it's a difference between boys and girls - girls seem to make eye contact sooner.
As for the feeding, it can take them quite a while to get it down. He sounds completely normal to me. As for the fast milk let down, I had that problem too and after a while my son caught on and learned to swallow fast enough. It did take a while though. It all sounds pretty similar to my son;-)
