I got my baby last Feb in the Queensway hospital, I prepare all by myself since they are required in the checklist. But I got vasline, swipe cloth, formular from the hospital. I guess you can also get diaper from them, too.
But I am very tired at that time, no energy to take care so routine issue.
Also remember to bring in some baby lotion for your new baby since it will have a bath in the hospital. And it is good to keep baby skin moisture.
Good luck...
