I'm Swedish, but we live in New Zealand. We might move back to Sweden soon, though!
I think there are extremely few Swedes (or Americans living in Sweden) on Mothering. Your friend might want to check out Sjalbarn, www.sjalbarn.se , which is the forum were you find people in Sweden who practice baby wearing, but also cloth diapering, extended breastfeeding, EC, AP, natural living etc! There are lots of them in Stockholm!
