Re: whether to pump morning excess
with the PP: at 6 months, your supply is probably quite well established and unless you are working outside the home, you probably don't need to worry about pumping so long as you are feeding on demand.
6 months is a common time for a growth spurt, so it's possible that the reason your baby seems dissatisfied with your supply is that he is trying to boost it with more frequent nursing. If that is the case, shelving the bottles, stopping the supplementing, and nursing as frequently as possible is probably the best and quickest way to boost your supply up to where your LO will be happy with it.
