K.,
Congratulations!
I was very very lucky with my son who was able to nurse as well as take a bottle and I feel very strongly it was because we had the right combination of breast and bottle and I hope you will have the same luck.
This is what worked for us: 1. Medela Pump in Style Advanced Back Pack: it doubled as a purse for me and I was able to set it up on my desk at work, plug it into the wall and pump while I worked. Make sure you do not rely on the battery pack. It doesn't give the pump near enough power. I bought an extra AC power adaptor and kept one plugged in at work and one plugged in at my desk at home where I pumped at night and this way all I had to do was plug the pump in and no untangling the cord and crawling on the floor each time to plug it in. If you ever want any other tips, don't hesitate to ask me. Go to this link for the best prices ever: http://mybreastpump.com/
2. Hands Free flange holder called the Original Pumpin' Pal. Check out this link: http://www.pumpinpal.com/New_HTML/original_page.htm
This thing was awesome! It took some getting used to but then I don't know how I got anything done without it.
3. Bottles: I loved the Playtex Nurser and Drop-Ins System combined with the One Step® Breast Milk Storage Kit. Those are the exact product names. I really believe that this system is what enabled me to be able to nurse my son for so long. Here is why: the nipples are pretty close to the real thing. They are silicone so they clean easier, don't have a weird taste and keep bacteria like latex plus you can see through them easier to see how much milk is getting into baby. The clean up is much less hassle since you're only washing nipples and collars. The liners get tossed. You can use the Parent's Choice knock off liners, but make sure you squeeze them lightly once you fill them with milk to check for leaks. A couple of them busted on me, you just have to check first before putting the filled one in your cooler. If you get the One Step Storage kit, it comes with an adapter ring that fits the Medela flanges. These are great because you pump directly into them and then they go directly into the bottle nurser and there is not a drop wasted, spilled or missed. It has to be the most sanitary way. You warm the breast milk by dunking it into a warm cup of water. (Never microwave it)
All you need to get are 2 packages to have this complete system: 1.) the One Step® Breast Milk Storage Kit and 2.) The Premium Nurser Newborn Gift Set. These 2 packages will give you everything you'll need to store and feed your new baby. I sound like an advertisement now, but that's how much I really believe in these products.
Well, I wish you the best of luck. I pumped this way for 7 months and now I'm a SAHM and my son is going on 11 months and we're still nursing very successfully! I was a text book case for everything that could go wrong for breastfeeding since I had a C-section, so I am very very lucky and I think doing the research and getting the right products helped with that success.
If you have any other questions, don't hesitate to ask. If I can help another mother to keep breastfeeding alive and popular, I will do it!
All the best!
