With more mothers needing to go back to work almost right away after childbirth, whether they be single Moms using a daycare provider or a working Mom who has a house husband, there needs to be something to assist them in making sure their baby gets fed properly while they are at work. Breast milk storage bags and pumps have come into being to help with this by being able to be there when Mom isn't.
The Medela milk storage bag was made to be pumped into directly and then stored for future use making them very convenient. These 5 ounce bags are the perfect size for feeding a newborn baby. If 5 ounces is more than is used at one feeding, then filling them half way works just as well and cuts down on the thawing time too.
If more milk storage is need, the Lansinoh bag holds up to 10 ounces and has a double zip lock closure. This makes this bag much more secure for freezing purposes and reduces the likelihood of waste. The only issue with the Lansinoh bag is that it cannot be pumped directly into as the Medela bag can.
There were reports of both styles of bags leaking, but later it was revealed that this was due to overfilling. Since freezing a liquid causes expansion, this would occur with any bag that had been used in this manner. Of the two, the Lansinoh bag has the better closure for freezing storage and larger capacity.
While both bags have their drawbacks and their good qualities, it is ultimately up to you, the user. Convenience of pumping direct as offer by Medela or the secure storage closure and larger capacity of the Lansinoh bag. The choice is yours.
