Re: Washing bottles
I had that problem with my first child. This time I've switched to Babyganics brand (available at babiesrus or amazon). I usually wash in the dishwasher with their dishwasher detergent and a little bowl of vinegar. The detergent is expensive, but you only use a small amount and it lasts forever. The few times I've soaked in hot water with their bottle soap has also worked great.
