Question about using frozen milk

nicole0066

I was pumping to supplement until my DD was able to successfully breastfeed after dealing with not getting enough from being born early.  I started a freezer stash since I was pumping more than she would eat.  I know the milk I pumped was "made" for her at this age but will it be good for her when I go back to work late August?  I know it can be frozen that long I just want to make sure it will be nutritious enough.
