Hi,
It seems to me that your recent problem with the biting has co-incided with a new developmental stage. he sounds like a normal 10mnth ld - finding it hard to sit still and do anything - like eat- when there is so much going on. If he is thirsty, give him water. if he is hungry, give him food. If he is thirsty he will drink water or breastmilk - he knows how the system works. Trying to make him breastfeed will only cause frustration. Offer, always, but set your body language to neutral - don't take it personally if he refused. Your milk won't *dry up* or any of those things people scare you about.
