Curious...how old is your LO? Formula or BF? And how frequently does he or she feed?

LO is almost 8 weeks and still very much on a 2 hour feeding schedule. I had thought that as she got a little older, she'd be able to space this out a bit further during the day. But it seems that she has been getting even more demanding, starting to fuss to nurse after only an hour and a half or so. Will we ever be able to space this out to every three hours??
