Query: Perfect fit!

This is the perfect size. Not too big - not too small. I can fit four regular sized bottles or three wide bottles in here. I can also fit my breast-pump parts. Today at work I brought three Avent (wide) bottles and my Avent Isis Manual pump and was able to fit it all in this bag along with two ice packs. It kept my milk cool for 8 hours while I was at work. I never put it in the refrigerator and it works great! I kind of want another one. This will also be perfect when my little guy starts eating food. A great lunch bag!
