I used an insulted tumbler around 600ml in size. My confinement nanny recommends drinking boiled warm water. That is the best. Else, I drink red date water. You will need to drink a lot when pumping milk so I suggest a bigger volume water bottle so you don’t have to keep refilling.
I use a big 2L water bottle. I refill room temp water, sometimes inside aircon room too long then water become “colder” so I get bonus 😂.
I drank room temp water, put a hydro flask beside my bed for convenience

I drank room temperature water!
