My friend delivered at Gleneagles Singapore last year with epidural and normal delivery, she said her total bill (including 3 days 2 nights single room) came up to roughly $8,000-$10,000 SGD
all in lah, but that's already including her gynae fees which can vary quite a lot depending on which doctor you pick. Someone in my mum WhatsApp group mentioned that on top of the package, got additional charges for things like paediatrician visit for baby, nursery fees, and any extra meds they give you during labour, so really must factor those in!
Medisave can offset a portion, and if you have private insurance even better lah. Gleneagles is really atas and the service quite shiok, most mummies I know love the experience there, just go in with eyes open on the cost ya!
