Sepata, DS is old enough now that if your supply dips a bit he can build it back up again for you. The main concern with two days' break is engorgement - even after 12 months, you'd be surprised how quickly you can become engorged. Express a little by hand if you feel discomfort and get DS back onto the boob as soon as you get home.

You'll be ok to wait for the pump. I wouldn't bother with the tea - many mothers find these sort of homeopathic remedies don't really do much and if you're financially strapped, I wouldn't bother.
