The Playtex Nurser system is the best system for breastfeeding mothers to use when they need to pump or give their baby formula.  This system is more natural and like the mothers breast than any other system.

The system has liners that are thrown away after each use.  These liners are sanitary and ready to use.  The liners empty like the breast, which allows for less air to enter into the babies stomach.  The less air that the baby swallows, the less likely the baby will get fussy due to gas pains.

The system allows for different choices of silicon and latex nippels.  The nipples are NaturaLatch nipples and are the closest to the mother nipple than any other nipple on the market. 

These bottles come in 4 oz and 8oz.  They are avaliable in different colors.  They also have the handy drop in liners. 

You can buy these bottles at all major retailers nation wide and they are often found on eBay auctions!
