Ivy, lots of fluid, rest and don't stress, that's the way to go. I know, easier said than done, but hang on in there, like what dolphingal said, who knows the next thing, you'll be bursting with supply! Keep getting the baby to suckle, tiring for you, but that's a good way to stimulate supply. ALternatively, like what I mentioned before, supplement with formula at night, but you continue pumping. I used the pump throughout both pregnancies and even when my hubby woke up to do night feeds, I still faithfully wake up every 2-3 hours, every night, just to pump. I had so much supply that I was giving it to my nephews. Same for the second one, though I must admit, less faithful...woke up every 3-4 hours, haha!
Papaya soup worked for me, doesn't matter whether with fish or pork, it's the papaya fruit. That's why they say, want fuller breast? drink papaya milk.
Need help, give us a shout, I'm sure one of us can come round, right gals?
