Has anyone experience leakage with Avent milk bag? I had to throw away my thawed milk. =(

A few of my friends are using Avent milk bags and none had experienced any leakages. If it happened to all the bags that you've purchased, I would suggest that you contact Philips Avent to see if they can offer any solutions. http://www.philips.com.sg/c-w/support-home/support-contact-page.html
