I stayed with now ex il’s about 20 years ago for 2 weeks that was time difference between been evicted from our house ( was been sold ) and moving into new one .
it was only two weeks but a very long one . We were not really made to feel comfortable - slept in the lounge as cat slept in spare room and shouldn’t be made to feel uncomfortable . I had a migraine one day so got to sleep in kitchen dinner next to dog bed .
Her cooking was quite bland . I cooked a roast dinner to say thank you . It was pie has to have his dinner at 5- I mean it was chicken , so if it wasn’t cooked it was going to be late . It was a great meal pil loved it that upset mil. We had to watch what they wanted to watch on Tv , couldn’t go to our room early as we had to wait for bedtime . It goes on really
i just put this as an example of how tough it can be .
My advice sit down have a conversation about your and there expectations - do you all want cooking rota or cook your own if you work very different hours .
I wouldn’t move out when baby comes but let her know she is welcome to have family and friends over . How will that be managed if you have friends over too .
cleaning , basic expectations .washing
Maybe gave them over for a meal to discuss this stuff .
Be clear you want this to work so trying to work a way that works for everyone first .
