I recently downloaded Hearthfire and have just finished building my house, Lakeview Manor, and decorating my interior so I chose to adopt two children, Alesan and Sofie. Once they arrived at my house everything sent fine, Sofie brought me some flowers and both children played a few games with me. I then went out questing for a day or two and returned to Lakeview Manor. Once i had arrived Alesan started a conversation with me for no reason, which would be fine but now he follows me around the house continuously starting conversations with my character making me very annoyed as I walk through the house. I have given him the wooden sword previously and have tried every dialogue option to make him stop, but nothing works. Is there any way of fixing this?

Kids seek out attention from their parents. Remember when you were a kid and bugged your parents for some toy or other? This is payback.
