Going Dairy Free and Pumping

livinreality

We think that DS2 is intolerant of milk so I am going dairy free (Day 6, thank goodness for coconut milk!)... everything I read says it takes 2 weeks to get out of your system. When would it be okay to pump and freeze the milk?  After day 14? 

We have been using pumped milk so DH can feed LO once a day during the weekends.  Should I toss anything I have already pumped and stored?

Thanks for any thoughts or suggestions!
