Adoption isn't very extensive at all. Get a note asking you to visit the orphanage. Go to orpanage, answer a few questions, pick out a kid. And/or you can adopt one of a few new orphans found around Skyrim. When they move in with you they'll bug you a lot to play, or ask if you brought them any gifts, or ask for an allowancem, or sometimes give you stuff. I had my son bring home a baby Skeever for a pet, and my two kids have argued with each other a couple times. That's about it.
