Beard which is becoming bald

Q: I have a full grown beard and the problem is it's balding in patches and it's falling a lot. What should I do or can I remove it an take some treatment an see how it grows again?

Dream

Q: In my dream I saw my father who had passed away a long time back. His dead body was in our house as though he died just now. I saw my dead grand mother also. My mom was going to give ghusl to my father's dead body. So I was telling my grand mother how can my mom give gusl? She is already sick and a weak person. But after that I saw my mom giving ghusl to my father's dead body. She put hot water on him.

Note: Nowadays my mom is little weak, just recovered from a long illness.

Custody of children

Q: When a man has divorced his wife and they have children so the small children are by the wife. However, he is allowed to visit them. But the problem is that the husband wants the children to spend the weekends by him i.e. that is he wants them to spend the nights as well by him on Friday and Saturday. But the wife says that they may only spend the days a the husbands home, not the nights. Is it correct for the wife to say so?
