As some of you know I"m bottle feeding a premie baby goat..He was born friday and his doing well....my question is..I've been warming his milk in the microwave for about 20 sec. I was told that microwaving is a no no...so, all day today I've been running it under hot water which takes soooo much longer. Whats your opinion on this??? Microwave or not?!?!?!?
