You`ll find your hospital will most likely have brest pumps on hand, I have never expressed and I have breastfed both my sons #1 till 14months and #2 I`m still breastfeeding @ 10.5 months.

As for jaundice, the midwives will suggest that you breastfed as the breastmilk is the best thing to reduce the jaundice, sunlight helps also but breastmilk is the best.
