Have you used the drop-in liners before? They do have some downsides such as the measurements not being accurate so if you mixing formula you have to mix it in a separate bottle or container first.

Are you using them with formula? What I have done is to use the bags as premixed "kits." I measured in the number of scoops and folded up the bags (not the bottle shaped liners) then taped them shut. I then lined the bottle with one bag, and dropped in my premeasured kits. Then when the time came I added the water.

I did find that the measurements were not exact like MrsBells mentioned. I do like the stiffer liners better, and I'd recommend getting the bigger 8 oz size bottles and liners over the 4 oz. More room to "shake!!!"
