If she's into the "earth mother" concept, a good gift for her (actually, for any new mom) is a sling or kangaroo carrier. My second child was fussier than my first and she liked to be next to me (ha, she's 8 now and STILL likes to be as close to me as possible). I could cook, do housework, read, go online, whatever, with her in the carrier. Some moms even nurse with a baby in a sling, but I didn't master that particular skill.
My brother and his wife are Birkenstock-wearing, mountain bike-riding, folk-festival attending, environmentally-conscious "granola" types. It's all good, even if they annoy the crap out of me at times. They were determined to use cloth diapers when their daughter was born. I ventured to suggest that the cloth diapers probably wouldn't be too convenient when travelling (they love to travel and do so regularly) or even when just visiting or going shopping. They pooh-pooh'd me, the SUV-driving, boxed mac 'n' cheese-cooking soccer mom that I am. Yeah, well, I got the last laugh on that one. My SIL also has a huge issue with gender stereotypes and disdains any kind of "girl" clothes or colours for my beautiful niece. On his last trip out, my husband brought my niece a box of my girls' old Barbies and some dress-up clothes - as frou-frou, pink and sparkly as one could imagine. My mom gleefully reports that my niece went absolutely bonkers with joy over this new bounty, and is now taken with the idea of being a ballerina. So she can wear a tutu. I am gonna be in deep s(&! with them when I go home in a couple weeks to visit. But I have to say, this has brought me & my own mom closer together...it's one of the very rare occasions where we're in agreement and on the same side.
