I had my PIL's stay for a month following the birth of DS2, and apart from Christmas day it was awful. I felt under pressure to keep a clean and tidy house, cook all meals, etc. I also could not allow myself to slob around in my pj's all day because I was worried they would think I was a slob. Of course they made no expectations of me but I was not relaxed enough around them to allow them to help and as a result my babymoon was disrupted and I did not enjoy that time.

If I could do my time again I would ask them not to visit for a month or so after the birth, unless they were willing to stay in a hotel and just visit for an hour or so every couple of days.
