A son should be good with his mother at the same time he can't ignore the wife also. At the same time by seeing his wife he shouldn't forget his mother also. But in our country, it happens many places two of them can't go together which will be a nightmare for the male in between both of them. If he is trying to convince them they will not accept each other and unnecessarily create problems for all.
So people should understand the philosophy of life and try to be good with the other members of the family and neighbours and live happily. Any moment we may be called back. This point is to be kept in mind for all purposes.
For fricitions in the family life, accept the situation sometimes make this worse as it means to give up trying to improve.
The son, mother and daughter-in-law should know that these fricitions happen in many homes. What is the need of the hour is an understanding of the changing dynamics. The son's devotion towards mother, now has to be shared with the daughter-in-law. The difference of opinions and views of the mother and daughter-in-law are bound to arise.
The son should now learn to ignore few minor complaints from both parties, try to make peace with both of them and give space and respect for both. Make mother and his wife understand that both are important and try being a responsible son and a husband.
Choosing sides or ignoring one of them is going to make things worse and at the same time just accept the situation is not going to improve things He has to put his efforts to get both of them to understand each other.
