Samval,
Yes, there's a slight warm feeling on the head after washing hair.
Miaiko,
If you want to be strict, not supposed to bathe at all! But if you think about it, it's really unhygenic, esp if you're breastfeeding.... After delivery we'll be bleeding down there, and once we get home, we'll probably perspire lots. There were times when I didn't know if my bb was having sweat or milk!! Not that I didn't bathe, but it was just warm.
For my 1st child, as soon as I was wheeled into the room after delivery, I bathed! Was in labour nearly 24 hours mah.
For my 2nd child, I had bathed just before going to the hospital, and the delivery was just 4 hours later, so I didn't bathe right after delivery, and in the end waited til I came home the next day to bathe.
