When my daughter had her second baby she wanted me to go and stay with her to help out when she arrived home from hospital, and my husband and son wanted to come too. Her husband is not exactly helpful around the house, or with their son, and she knew that either she would be getting stressed with him or be struggling, after a caesarean, to try to do it all herself.
So we went down and stayed in a B&B. I shopped before we arrived each day, did the washing, made meals and my males kept my grandson out of the way while SiL played on his Xbox. My daughter was very grateful, but on day 3 SiL had a bit of a wobbly and said that he wanted his family to himself. My daughter was very upset - when she had their son her MiL had stayed for weeks and had barely allowed me near to the baby! She wanted me to stay and said that he would get over it, but I decided that we had better cut the week short and leave the next day, rather than cause them to row with each other.
I still feel a bit resentful, but better that than cause huge rifts in all directions. They come up to stay with us for a week at a time three times a year, so I was surprised at his not wanting us there. I preferred being in a B&B, I'm sure we got far more sleep than we would have done if we had stayed with them.
I must have a look for the past threads, it was very upsetting at the time but now I think it was all down to SiL's tiredness and his just wanting things to get back to normal.
