My ebf pfb is 7 weeks old and this week has discovered sucking his hands, and very noisily at that! I've always read that this is a sign of hunger, but even after a big feed with both breasts he's sucking away at a fist a few minutes later... so I try to feed him again, he'll sometimes suck a little but doesn't seem very interested. Just wondering if he's telling me he's still hungry or if he's just enjoying his new discovery?
