"extended" nursing and supply

Ok, so 14 months into this.... ;-)
I really wonder how much milk DS is getting. He fairly often falls
asleep against me, without nursing...just wants a face full of booby And
letdowns take FOREVER, and now that I don't feel them much at all I only
have his swallowing to go on...which suggests there ISN'T much letdown
happening most of the time....

So.....are we weaning?? (I've asked this before) He mostly only nurses
to sleep now, and some mornings doesn't have much interest either, and I
am never "full" or even sure which side to offer, even if he hasn't
nursed for 12+ hrs on one side (ie, if he nurses to sleep on teh left
side, and doesn't nurse again til 7am, he may not have nursed on the
right since noon, but the right side won't feel fuller)

I managed to pump 2-3 oz a few weeks ago, but rarely manage more than a
tiny bit, when I try. I miss that, watching and feeling all that milk
spraying out when I pumped.....weird, and I know, obviously if I miss it
it just means I didn't do it often enough to be glad to quit.... ;-)
