What do you all think

Okay so I have a friend she lives in the same complex as I do. We hang out a lot!!!! She has a baby girl and lives with the daddy.... Her mom lives in another house but comes and visits!!!! They have an apartment with two bedrooms right well the mom comes like twice a week and stays over. Before she would stay in the other room but because of the baby they moved the extra mattress to th their room. Where do you think the mom sleeps when she comes????? They all sleep in the same room. My husband would be like ah no your mom can't sleep in the same room as us. My friend finds it okay but we see her bf seems bothered! What do you all think? By the way his family is not allowed to visit them without being invited? But her mom stays with them like once or twice a week! And if my friend and her baby sleep in the same bed either he has to sleep with my friends mom or in the couch.
