Q from a former pumper with a stash left.

EveryNameIWantIsTaken

I pumped for dd until she was right at 4 months old.  Then I stopped because it was just a lot of work and taking too much time away from my 3 year old and life in general.  I had a good freezer stash going, and was planning on feeding dd that.  Well, the frozen stuff gave her MAJOR gas issues.  She'd been gassy when eating the fresh pumped, but nothing like the frozen milk.  So, we switched to just formula and it got about 10 times better, hardly any gas.  Now I am left with 5 gallon sized bags filled with lansinoh bags containing anywhere from 4-7oz per bag.  I hate to toss all that work down the drain, but I'm also hesitant to donate because I worry of a lipase problem.  The thawed milk never smelled weird, it's just the fact that it made dd so gassy.  WWYD?  I am looking into a local Eats of Feets chapter, but just worry.
