If you pump, Medela supplies are all BPA free and have been for a long time.

Also, BPA is not really harmful if you hand wash your bottles, don't microwave them, and don't use extremely abrasive brushes/sponges (like a scouring pad) or extremely corrosive soaps. If you use standard bottle brushes and baby-friendly dish soap, then you're fine and you don't have to find new bottles.

We used a BornFree sippy which was okay. Mostly we used a regular cup and held it for baby until baby got the hang of the tipping/sipping (practice in the bathtub).
