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...

My friend recently purchased Pacific Baby, which is a thermal milk bottle. This helps to keep the milk at a constant temperature for at least a few hours and you can also feed directly without having to mix milk powder and water when you are outside. The downside is that it is rather heavy. http://www.amazon.com/Pacific-Baby-Bottle-Blueberries-Ounce/dp/B0085P4Z6M/ref=sr_1_6_s_it?s=baby-products&ie=UTF8&qid=1451399202&sr=1-6&keywords=pacific+baby
