Recently granted guardianship over my teen brother. He wants me to sleep in the room with him everyday. Should I address this or wait it out?

I have been granted guardianship of my 15 year old brother. My mom left on Tuesday and my brother has been living with me since then. Every night so far he has asked me to sleep with him.At first he didn't want to sleep in his bedroom so we slept in the living room together. Now he is in his bedroom but wants me to stay in here with him. I am currently laying on the floor getting ready to go to bed. The other night I snuck out after he had fallen asleep. He came into my room and waited for me to wake up once he realized. I don't mind sleeping on the floor all night but I haven't addressed this with him yet. I assume it's because he's missing our mom but he says he's fine without her and is happy to be with me. I've always been more of a parent figure to him anyway. He looks happier than he was before. He is sleeping much better and appears to be in a brighter mood. He doesn't talk about his feelings a lot and I don't want to push him sleeping in his own room and make him feel like I don't want to be around him or that he's weird for wanting me to be with him.I imagine he will stop at some point. Do I address it or wait it out? via /r/Parenting https://ift.tt/2xdCXJC
