Ways of Cooling
There are three ways to preserve the milk depending on how the cooler bag is constructed. The most popular method is the use of ice pack. Here, an ice pack is inserted to keep the milk cold, fresh and safe in the outdoor trips.
The next method is the use of gel lined coolers. You’re supposed to refrigerate the gel overnight ahead of use. For that reason, they’re not that convenient for random trips.
A rare but efficient choice is the use of portable refrigerator bag. The method will need you to connect the bag to a power source or car battery to maintain the milk at cold temperatures.
Capacity
The best cooler bag is divided into at least two large compartments: the upper and bottom parts; and a back & front pocket. There are a few models with other extra pockets to meet your storage needs.
Additional pockets are essential to store your snacks and other baby accessories so there will be no need for an extra lunch bag. We suggest you pick a cooler bag that fits short bottles as well as tall baby bottles of 9oz.
Waterproof Lining
The purpose of the lining is to shield the rest of the stuff in the event of mess or leakage. A waterproof bag is easy to wipe since the wetness will not penetrate into neighboring compartments.
Straps
When shopping for a cooler bag, check the design of the shoulder straps to see if you can wear as crossbody bag. The reason for this is because you probably have to carry some other things with you as you head to the daycare.
Versatility
A versatile cooler bag can be transformed into a regular bag if you’re no longer pumping. You should be able to detach the divider and use the bag for ordinally purposes.
