Re: cleaning and sterilizing pump
hi mama! yes, ok to reuse for the day if you keep everything in the fridge. also no need to sterilize unless your baby has a vulnerable immune system (preemie or illness). i sterilized maybe once every 3 months or so. ditto for bottles, no need to sterilize, though i probably wouldn't use the same unwashed bottle for more than one feed, because milk tends to go bad faster when it's been warmed, and you'll always have a little left over on the sides that you won't want mixing with the fresh milk.
