Philips AVENT BPA Free Breast Milk Storage Set

These bottles can be attached to the Lansinoh Double Electric Breast Pump - 1 Count using the Avent Breastpump Conversion Set. You pump straight into the bottle that your husband or babysitter uses for feeding your baby. No fats and/or vitamins lost during the transfer of contents from bags or other containers. I chose this bottles because they are BPA free.

I've used these several times now--and they don't leak. I can shake breastmilk as vigorously as I want--there is still no leakage. They are also easy to clean--wish the mouth was a little wider so that my hand can get inside, but it is wide enough (46 mm inner diameter) and short enough (4 0z bottle is 82 mm from interior base to top of lip) that I can get a sponge in there without a struggle, making a bottle brush unnecessary. This is the cheapest, non-disposable, volumetric, BPA-free, wide-mouth milk storage solution that I have found--perfect for taking expressed milk to daycare. I liked these so much that I just bought more. Note that these bottles are a little honey tinged, but that is just a property of the BPA-free plastic that Avent uses.

I switched to Avent from Playtex drop ins. I had 1 Avent bottle and i noticed my son took to the nipple, so i bought a few more and after a few weeks i noticed he NEVER spit up anymore. So i made the complete switch and i even bought an Avent ISIS iq double pump too. Best decision i have ever made.
Now the thing i noticed, is the Avent bottles that have the 1 piece and even the ones with the 2 piece anti-colic valves tend to sometimes leak... even when done correctly! My son would get halfway through a bottle and all of a sudden it would just leak! drives me crazy!
I dont know if its just luck or not, but these have not leaked at all!!!!!!!!! I make sure i use these instead of the regular 4ox or 9oz bottles. these in my opinion are waaaay better!!!

UPDATE 12/27/2010: Recently had a few minor leaks, minor because i caught them at the beginning of the leak. I dont know what it is with avent... its not at the beginning of the feeding, but more towards halfway...Read more
