My 10 week old has been feeding constantly for 2 days. He seems totally frantic for milk. I would have put it down to a growth spurt but there's not one due around now. I keep trying to hear him swallowing but I can't, although I've never been able to. I just assumed he swallowed quietly because he's been gaining plenty of weight and is on the 91st centile. He's still having wet and dirty nappies but I honestly can't put him down because he'll start rooting. I'm really concerned I don't have enough milk and that he's going hungry :(
