Hi! Harris is 9 weeks old tomorrow. Last Thurs (7+6) he weighed 11lb 13oz. I am sure he will be over 12lb now.
As for feeding, I actually have no idea how much he actually eats! He never takes just 5 feeds of 5/6oz though. I would estimate that he has about 27oz per day, but I think a 12lb baby should be drinking 30oz? Apparently, you multiply 2.5oz per lb...
