You might visit the Postpartum and Birth Loss forums and ask the mamas what they would recommend. If you know her well enough, go and clean her house, do some laundry, and if you can bring a few meals, as the PP said, that's awesome. I read somewhere on MDC about a mama who organized a food tree, kind of like a phone tree, where a group of families got together and made meals for the grieving family for a couple of months, I think. That's incredibly helpful when it is all you can do to eat even a little. Often cooking can just be too much to face. Then people don't eat enough and have even fewer resources to deal with their loss. Definitely make contact.
