These bottles are my favorite along with Avent. I first used Avent 10 years ago with my first born and Born free with my second and third. These bottles are affordable and more importantly they get job done effectively. I introduced a bottle to all three of my children at 6 months old and transitioning from nursing to bottle feeding couldn't have been easier for them.

I liked the Born Free bottle for its durability and baby-friendly design. However, it's anti-colic vent system left me with a lot of parts to wash, assemble and keep track of.
