I use these when at work. They are great!
At home, just use a pirex bakeware thing with cover, add your washed pieces and 3 oz of water, microwave for about 2 minutes. It steams just like this bag does, but you don't have to buy more just for use at home!
With my first daughter I had to pack 3 sets of pumping supplies to pump each time...this meant for a long night of washing between nursings and sterilizing the items. With these wipes I can use the same supplies all day and it has been a HUGE help! Especially since I have a newborn & very active toddler on my hands. I would highly recommend these to moms! I also keep a pack in the diaper bag to wipe the paci or toy that falls to the floor.
I love all the Medela products!
When pumping at work or somewhere not so ideal, my car for example, these wipes have came in handy! They are a quick fix for cleaning it and then I can do the deep clean on all the parts when I am home. Love it and would absouletly recommend these!
