Need a Cooler capable of keeping Baby Bottles chilled for longer?

So there are baby bottle cooler bags in the market for the specific purpose of keeping your breast milk bottles cool.

But these will only keep them cool for a few hours, and even the best will not go more than a day. What if you want your breast milk bottles to last longer?

In that case, you can use a regular soft cooler to do the job. Perhaps in the case of baby bottles, you won’t put in too much ice to avoid freezing the baby bottles. But then again, surely there isn’t anything wrong with putting in a little ice.
