ds is now 6 weeks old and had been breast feeding well, usually taking both breasts at each feed and spending 20-30 minutes on each. The last 3 days he's suddenly started to cry out, take himself off the nipple and then immediately try and get it back. I've tried winding him but this doesn't seem to be the problem. It happens most but not every feed. Any ideas why? It usually happens after about 10 minutes, although can happen slightly earlier.
