就系lor... "i think" just the selling point.... haha
um.... "i think" depends on the baby...
for my experience, my son & his cousin (they were born in same week) used pigeon, my son just spent 1/2 hr for drinking milk, change nappy &掃風, so I can sleep 3 hrs every time; but his cousin need more than 2hrs to finish all the thing, so my sister-in-law just have a bit time to take rest...
