hospital will provide a pack of diaper for bb to use, it's sufficient for 2d1n. u get to bring balance home.
hospital also carries assorted instant formula milk, so don't have to bring along. unless u decided on a specific brand that's not generally taken. eg my friend is a vegetarian n brought her own milk powder along.
my bb drank Nan optipro while in hospital for 2 days n have been on breast milk thereafter
