I'm a bad mommy, but after sterilizing the bottles and nipples the first time I used them, I never sterilized again. I just ran them through the dishwasher.
Actually, I did read somewhere that was fine and there was really no need to sterilize everytime. I think it's more an issue if your daughter was a preemie or has a compromised immune system. My daughter is 4 1/2 and fine. No lasting ill effects from my "neglect" in that area. I look at it this way... I breastfed and never sterilized my nipples before feeding her. Just washed in the shower in the morning. And a lot of books on breastfeeding recommend against using harsh soap because you don't want to further dry out your nipples when they are often already tender, chapped, or cracked from the almost constant nursing that occurs in the first few weeks. (Sorry if that's TMI.)
As for the condensation in the bottles, I laid clean papertowels on the counter and stood the bottles upside down on those. They dried within a few hours I believe. If you don't want to do that, there are bottle drying racks you can buy. You can find them at Target or Babies R Us.
As for breastmilk in the bottle when it has condensation in it, that's fine. You sterilized them so it's not as though there's anything harmful lurking in the condensation. I will caution you a little regarding starting a bottle at 6 days if your DW is trying to breastfeed. It is generally recommended that you stick with exclusive breastfeeding for the first 2-3 weeks for a couple reasons. One being that your DW needs to establish her milk supply. Pumping just doesn't stimulate the milk production as well as baby sucking. Babies are much more efficient at draining the milk than a pump. Secondly, there is a belief that switching between bottle and breast can cause "nipple confusion". Babies suck differently from a bottle than they do from a breast and you want baby to get proficient at nursing first before introducing the bottle. I've also seen some articles that dispute this so take it for what it's worth. Honestly, for me, nursing was a million times easier than pumping so I much preferred to nurse, especially in the first month. But definitely introduce the bottle no later than 3 weeks. You don't want baby to get so attached to the breast that they don't want the bottle.
Sorry if this is a much longer response than you wanted. Congrats on your new DD!
Being a new parent has to be one of the most nerve wrecking experiences. I know in the beginning I worried about every tiny detail. It takes a little while, but eventually you gain a little confidence in your parenting abilities and you relax a little. Thanks for giving me the opportunity to reflect on those incredible first weeks of my daughter's life.
