I will be pumping at work for the first time tomorrow. I purchased Playtex's Fridge to Go, which has frozen walls in it to keep things cold for 12 hours.
My milk is fine in the fridge for a few days, but once frozen can get the sour smell due to high lipase. Being that the Playtex cooler might freeze the milk a bit since it gets so cold, should I worry about the milk breaking down? Is the Medela cooler/ice pack good enough?
Thank you in advance for your support.
