My 12 week old preemie never latched on so I have been expressing milk and storing the extra, which has been a lot since I produce more than double what he eats. The only problem... we have been using storage bags, first gerber but now lanisoh and we have been using marker to write the date, under the ziplock, on the bag part. I just started to read the box and realized that could be a possible ink contamination. My lactation consultant says it should be fine but she can't be certain. I wrote above the milk line.
I don't want to throw out three months worth of food but I also don't want to get my son sick... HELP!
