hmm, my gal is over two months, and it's been difficult at night, I guess she gulp too much milk too fast, I can even hear the sound when she try to swollen down the milk. That normally means trouble, but sometimes burping just dont work. So it's quite easy to puke... and I got to feed, burp, puke, clean up... etc. Last night finally slept around 1am, then when I put her down, she cry again, so another feeding with not so full breast, milk flow slower so no need to burp, then she slept at 2am+, I'm so tired! But then she only wakes at 650am for next feed this time, at least got some rest for me. Didn't try Bao Ying Dan though, but you can ask Eu Yan Sang, they can tell u the dosage for young babies.
