All these are old wives' tales. It depends on how much you want to believe.
- Did not shower in hospital cos the aircon was very cold, I dont't want to catch a cold
- My mum installed hot water for the basin in her room's toilet so that I can wash my with warm water. I brush my teeth with warm water from the tap also
- My mum allowed me to bathe with boiled herbal water. But she said it's smelly, asked me to rinse with warm water after that. (cos I was sleeping with her on her bed)
- I only drank 1/2 cup of red date tea during whole confinement Cos my mum made it SO SWEET and SPICY with ginger! So I drank warm water throughout cos I was breastfeeding, need alot of water to produce milk
My mum is more modern and dont't really believe much in those old wives' tales. Esp since I always challenge her
Whether you need to follow strictly also depends on who is helping you with your confinement. If you do something they dont't 'allow', get ready to be nagged at
