Dear Mummies, may i know how do u keep the milk warm at constant temp (say 40 degree c.) during outing? I tried with Pigeon double bottle holder but it doesnt work...

It is not encouraged to keep your milk warm for a prolonged period of time as it encourages the growth of bacteria. If you need to bring out your milk for an outing, please bring it cold in a cooler bag then warm it up only when your baby is going to drink. I use a Tommee Tippee travel bottle & food warmer to bring hot water out to heat up my milk. If my baby doesn't finish the heated milk within an hour, I will discard it.
