Medela Nipples and Other Bottles

Gerber bottles work, and the caps fit the nipples as well. Bonus: they're cheap (about $1 per bottle) and now BPA-free. Yay!

The Gerber narrow mouth ones should fit. I used the medela nipples with the 4 ounce ones. I think most narrow mouth bottles will fit them. Since my DD would only use the small nipples, I just took one to Target and compared it to the nipples/holes in all the bottles. I bought the Gerber bottles in packs of 4 for like $5.

They also fit Dr. Brown's (regular size) bottles.

I've been using the Green to Grow BPA-free narrow-neck bottles with Medela nipples for the last 10 months. I love the Medela nipples and rings - their silicone seems softer than any other. I even use their silicone nipple with the Green to Grow ring when my Medela rings aren't clean yet. Any narrow-neck bottle will work (including the ready-to-feed formula bottles, newborn size or 6-8 oz, like Similac for instance). It is a standard narrow-neck size. Good luck!! I just switched to the faster flow (in Medela, this is termed Medium flow) kind when my son was ready, I never went to the wider-neck bottles and won't make the switch. Only narrow-neck bottles for me, so convenient because it is compatible with the awesome Medela system.

green to grow bottles fit medela nipples. HTH. :)
