Girls after giving birth to a child husband sleeps alone for a month after a month he goes to sleep in another room says to me tomorrow I have to go to work the child cries can't sleep I am upset and said you won't sleep alone I will go to my mother to sleep alone until 2-3 hours at night and as the child starts crying going to another room. Do you think this is normal or does it negatively affect relationships? Have you had such a situation?
