For A1 ward normal delivery at NUH, most mums I've heard from paid around $5,000, $8,000 cash out of pocket for a 2, 3 day stay, depending on whether they had epidural and which doctor they were under. My neighbour delivered there and her final bill came to about $5,300 cash for two days, which she said was reasonable once she factored in the doctor and baby fees as separate items. Just note that the baby's bill comes separately, so don't be caught off guard when you see two invoices!
