ordered a medela breast pump

what bottles would you suggest? Did you buy Medela bottles or just use another kind? It's Medela Pump in Style advanced and it comes with a kit. What else is necessary to have for breast feeding? I have one child already but did not breast feed him and I'm determined to do so with our daughter. Thanks for the help!  

The Medela Calma nipple has been my savior. I highly recommend it if you're breast feeding!

to be honest its hard when it comes to bottles. I have a 5 week old and we switched through 3 different kinds until we found the right one. we had Playtex drop ins at first and he wasn't doing to good, then tried nuk he didn't like the nipples and now were on the slow flow vent air Playtex and they work   Its really up too baby. Well in my case anyways
