I'm going back to work 6 weeks PP, but I'll still be "in the house". With DS I would use the boppy to hands free nurse him while I continued to work, which worked well with the exception of conference calls and when I got really super busy and just couldn't handle the interruption. At those points I would hands free pump and let the nanny give him a bottle instead.
I had read some things last time that if you want baby to be OK with taking a bottle, you should introduce it at 3 or 4 weeks, else they may not take it in place of the breast. I have heard first hand from moms about their baby that won't take a bottle, so I was pretty intent on not letting that happen. I introduced DS just shy of 4 weeks and he had no issues. So, I assumed I'd do the same again.
I don't know if I will want to pump vs. nurse at my desk this time, but I assume a combination of both. My office is no longer on the main living floor though, as I had to move to the basement to make room for baby. I'm a little concerned about having her brought up and down the stairs so much, just because I'm super paranoid and worry about an accident on the stairs while carrying her to/from me. I'm sure I'll get over that at some point... I hope.
It is probably something that /could/ wait, but I'm a bit nuts about being prepared and organized. So, one of the things on my list is to sterilize all the pump parts and bottles and whatnot... I don't know if I'll feel like messing with that pp necessarily, at least not before I'd want to pump so I can start building up a supply in the freezer. And I don't know if I'll want to deal with ordering new nips before I'd want to intro the bottle.
I think since I'm even just the slightest concerned, I'll just go ahead and order new ones. I only really used 6 of the ones we have, and those are the type I'll order since they work very well for making baby "work" to get milk the same way as at the breast so there's no "lazy" reaction to the boob later.
Thanks for responding... This is my second baby, so I don't know what's OK to reuse... well, nipples are the only thing in question right now I guess... unless there's anything else someone might suggest NOT reusing. :-?
