If a man sleeps in a room other than his wife's room because of the baby's crying, does he sin by doing so?

Question:
He says: Honorable Shaykh, may Allah grant you success. My wife gave birth six months ago, and I do not sleep with her; rather, I sleep in another room because of the disturbance caused by the newborn. Am I sinful for doing this?

Answer:
Yes, if there is a reason for you to sleep in one room and her in another, because this is more comfortable for you, for her, and for the children, there is nothing wrong with it. The purpose of sleeping in the same room is that you are present in the house, around her, with her, and she knows of you. That is the purpose; the purpose is the comfort of your presence. Yes.
