Ms_Tan. Yes. U sign up for package. But the package only includes bed, and food if i am not wrong. other consumables are chargable. I am sure you can give instructions of what you want to use, but too much of a hassle. And seriously, you will just want to rest after delivery. Everything else, just leave to the hospital to arrange.
Disposable undies, u can get nice comfy cottons ones! Don't get those paper kind lar. And yes, a lot of bleeding, so might stain. Unless you have a confinement lady to wash for u, better just stick to disposables. My MIL doing my confinement, i think very strange to ask her wash undies. =P
Andreanie: Right after delivery, the nurses just stuff like 2 pads under me. Haha... the loop kind. No idea if there's any underwear or not also. If no underwear, how to use adhesive ones? Anyway, after delivery, u will be confined to bed, the nurses will change for u etc, adhesive might be difficult for them lar.
What Ethan_Ethel said is correct for TMC. Every pack of cotton balls, pads, wipes, etc are all chargable. And all the left overs you can bring home. I brought home everything, except the loop pads. No idea how to use those lar!
