When my now-9-year-old was born, a friend gave me a Medela Pump in Style she had used for all 3 of her kids. I replaced all parts that touch milk, plus the tubing and electrical adapter, because everything was very worn. It worked really well for me, so when another friend was expecting (and I thought I would only have one child) I gave her the pump.
Now I am expecting again, that second friend's 2 kids are weaned, and to my amazement she offered to give back my pump! She came by last night with a huge storage tub full of stuff, which we couldn't look over because we were distracted by our kids and it was almost dinnertime, but she managed to tell me that she had gotten a second Pump in Style that was in there too, and that she had also included all the bottles she had.
Obviously I'll need to ask her why she got the second pump--was the first one getting unreliable? Was the second new or used?--but I'm hoping to get some guidance here about what to keep vs. replace.
(I will be using the pump a lot, as I plan to return to work full-time after 12 weeks.)
I'm inclined to replace parts that touch milk just because it seems more sanitary. Is this necessary? (As far as I know, my friend has no health problems that could be transmitted, and her second child has been weaned for almost 2 years so it seems that anything remaining on the pump parts would have died by now anyway, and I will boil everything....)
What about the tubing? It looks fine.
Some of the bottles are glass, and some are Medela plastic with the updated logo, i.e. newer than what I had for my son. The cover caps have her kid's name very indelibly written on them, so of course I'll replace those. Do I need to replace the nipples, or is sterilizing adequate?
The newer pump is missing its manual. The connectors on it look very different from the ones on the old pump; I can't find anything that looks quite like them on Medela's site, although they look more like the Freestyle connectors than the Pump in Style--but she said this was a newer Pump in Style, and the bag is almost identical to the old one.
