Help please

No judging please! I’m currently 39 weeks pregnant,I’m staying in a transitional home program where I have one other roommate and we share a house,I’ve been here for about 6 days and everything has been running smoothly,well about 3 days ago my roommate asked if I wanted to ride to Walmart and I agreed so as we got to talking she mentioned “it was times where I would sit and watch my son just screaming crying and I wouldn’t care” I assumed she suffered post patrum so of course I didn’t judge! But fast forwarding to this morning around 4:00 AM her son who is now 1 years old start crying and I heard her say repeatedly “shut the f*ck up” now I’m a complete reck because I’m getting ready to bring a newborn into this home and if she can’t handle a 1 year old crying how is she going to handle a newborn SCREAMING? our rooms are right in front of each other by the way so there’s no way she would not hear my baby. There is a lady over this program and I want to mention this to her,what would you do?
