V.T.
I use the Born Free as well, but just to let you know there is a valve that you have to use in each bottle. I tried not to use it and it leaked. So you still have 5 pieces to wash, but they are a lot easier to wash than the Dr. Browns. Since we travel a lot and the Born Free can take up space and hard to clean while traveling, we also use the Playtex Drop Ins, which my daughter also likes mainly because they are light weight and easier for her to hold herself. They are also an easy clean up since you throw out the plastic insert.
