I've gotten a fair amount of chances to feed Jonathan in the last few weeks, since sometimes when I'm there Mom has been going home. One night I stayed all night with Dad so Mom could sleep, and I've been there for an afternoon or two when Mom has gone home to see the other kids. I can now officially testify that Mom's milk DOES separate, with the cream making a pretty thick layer on the top. Also that this bottle-feeding stuff is for the birds...the only good part about it is that I get a chance to feed the baby now and then!
