In this system, you pump directly into a sturdy portion-sized freezer storage bag which gets slotted into the organized holder. (The freezer storage bag is compatible with any major pump brand.) When baby’s ready to eat, you thaw the milk using the included bottle warmer. Then you slide the storage bag into the bottle casing, and screw the nipple directly onto the bag, and your baby’s ready to drink.
The main merit of this system is you only have to wash the nipple (and your pump parts as necessary). The main downside of this system is you recycle the bags each time, and the cost of buying new can add up (they’re about 33 cents each when purchased in bulk). However, the system ensures that not a single drop of milk is wasted in transfer.
The starter kit comes with three different flow speeds and the nipples are designed to mimic a natural latch. But babies can be picky about what nipples they use. If your baby demands a different nipple, you can buy an adapter to use on other bottles Make sure to screw it on tight to prevent leaks. Also, because these are storage bags, not storage bottles, it can be difficult to tell the exact amount of milk inside of them, even with the measurements marked on them.
One thing that is really nice about the bags is they are so much stronger and sturdier than your typical bag and you don’t have to worry about them rupturing. Leave just a little bit of room inside them when you pump, since milk expands when freezing. Another thing to keep in mind is that freezing your milk isn’t necessary if the baby’s going to drink it the next day. The Mayo Clinic saysit’s fine to keep breast milk in your refrigerator for three days.
The bottle warmer included with the kit is an especially good one. It’s very easy to use: you just fill it with water up to the mark indicated, plug it in, and set the timer. You can use it to warm up baby food too as well as breastmilk. It’s easier to get milk to an exact temperature with a bottle warmer.
