Re: Baby feeds fine, but cannot pump...
It sounds like your wife may need a better pump. Since she's returning to work, a Medela Pump in Style is probably a good bet. She may also want to see a lactation consultant and have the LC watch her pump- there may be something that can be observed in person that we can't catch via the internet.
Shields that are too big can definitely impact milk output. As a first step, your wife might want to go down a size and see if that helps.
