Where do I get a bed for my child?
I want to adopt a local child (Lucy I think her name was) so I just bought a house in Whiterun. The problem is I don't have a child's bed.
Where would I buy or how do I make one?
Go talk to Proventus Avenicci, the steward in Dragon's Reach. He will have a dialogue option to purchase a children's bedroom, that of course contains one.
Further reading on him.
