Never really timed but the bowl of hot water works better for me. The time taken for the milk warmer is longer and you run the risk of the milk being too hot or not hot enough.
Hot water in cup/container for me, leave it there to thaw while I prepare other things. Milk warmer use electricity and need to change water and wash.. Aaah too much hassle.
bottle warmer all the while for me. hot water takes too long. milk warmer can adjust temp
Bottle warmer (75 degrees) takes abt 10mins, hot water (100 degrees) takes abt 5 mins.
using milk warmer!
I am using warmer
