Re: One week back at work and already frustrated. . .
Yes, your nanny is overfeeding your baby (unless you're at work 10+ hours a day). And your pumping output is GREAT!
The general rule is to leave 1-1.5 ounces per hour you are away from baby. Here is a good article with information about how much expressed milk a baby needs. Show that to your nanny if she tries to give you a hard time about baby needing more milk. Lots of care providers who are used to taking care of formula fed babies have this problem of giving too much breastmilk, but your baby shouldn't be taking more than 3, maybe 4 ounces per feeding. Do you leave bottles pre-made for her or does she have access to frozen milk? It might be worthwhile to fix her bottles- 3 ounces in each with a 1-2 ounce top-off bottle just in case baby is really hungry or going through a growth spurt. And you might want to share this article with her on how to bottle feed a breast-fed baby, with lots of tips on how to mimic nursing with a bottle and how to soothe a baby with a strong suckling instinct without giving more food than baby needs.
I know this wasn't exactly your question, but typically you should be trying to nurse/feed baby 8-12 times in a 24 hour period. I'm sure your baby is eating plenty, since it looks like she's getting half (or more) of what she needs daily from the nanny, but if you decrease that amount to a more reasonable level she will need to get more from you. Do you nurse at all overnight?
