how do you keep the bags in place? I decided to try this because I was sick of tranferring the milk and washing the bottles every night, but I'm not sure how to keep the bags on securely. (I tried a rubberband, but it did not seem that secure - and I don't want milk all over me!)
TIA!
Re: If you pump directly into the storage bags...
I use these too. They are called Pump and Save.
