In laws sleeping with me n my baby...Suggestion quick pls

div

I hv started staying with my in-laws yesterday with my 3 month old baby.

My husband lives in other country for job.

We have ground n first floor house here.

I have my bed room and a hall in first floor.

AC available only in hall but not in that bedroom since me or no one used that room frequently...

Since summer started here me n baby could not sleep in hot bedroom. So I planned to sleep in hall with AC but my in-laws also laying in that hall and not moving to ground floor or adjusting bz I hv a baby I need to feed 3 hrs once..

I told my MIL to ask my FIL to move to either my bedroom or ground-floor and she asked him but FIL dint not bothered and slept in same hall.. we all four were laying in same room..

Around 4 am baby woke and I was thinking about how to feed baby .. inbetween MIL asking me to turn other side to feed baby since FIL was also laying there. I felt so worried n irritated to feed like this.. and took my baby and things n shifted to that hot bedroom ...(hubby wil not bother)

My primary problem is where to sleep and how to convey it to in-laws..

Pls tell me Wat should I do today night. How to react.

WATS steps can be taken
