surely Lansinoh must have some idea how much time , sacrifice and emotion go into each and every ounce of breastmilk a mother pump to store for she baby . why on earth would you sell we something that leak so badly ?! I exclusively pump breastmilk for 9 1\/2 month to feed my daughter because we be unable to nurse . I store ton of milk in these Lansinoh bag in the freezer . if only I would have know before it come time to actually thaw the milk , how crappy these bag be , I would have switch to another brand 9 month ago ! probably about 75-80 % of these bag leak along the seam -lrb- many in multiple place -rrb- while thawing . now that I be on my last stash of milk today and have 99.9 % wean from pump , I have spend some time cry over my sink as the last few bag of milk for my little one spout fountain -lrb- that I can not quite capture into a bottle -rrb- out the bottom and side seam and run down the drain . yes , thanks a lot , Lansinoh , for make the last few remnant of liquid gold -lrb- that cost I so much emotionally already -rrb- cause I more stress and tear once again .
