The Lansinoh breastmilk storage bags are popular for their flat freezing design, labelling features, and general ease of use. However, a significant number of parents report frequent leaks, with milk seeping through the zippers or the bags splitting after freezing. While some find them reliable, others have had to discard large amounts of precious breastmilk due to these quality issues. Overall, they work well for many but the leakage risk is a major drawback to consider.
