My Daughter was a complete surprise, as in no idea until my partner went into labour. My DPs sister went to the hospital with her, and their mum was called and said she'd meet them at the hospital. She turned up 2 hours later, having missed the birth, but with everything we'd possibly need for the baby for the next month stashed in the back of the car.
My DP continued living with her parents for the next 3 months, until my house was ready for them to move in. Both MIL and FIL were fantastic the whole time.
My own mum was equally great, I phoned her up, dreading telling her that I'd had a child with someone I'd only been seeing for 10 months, and her first words were "fdgd, thats brilliant". Made me feel so relieved and that this wasn't the end of the world.
Both sides of the family have been so supportive over the last 11 years, financially, with childcare and just being fantastic grandparents.
My MIL died 5 years ago, just before Christmas. She knew she wasn't going to make it till Christmas, but she still spent time buying loads of daft christmas presents for us all, stuff that we'd laugh at, to try and cheer us up that Christmas.
My own Mum is struggling with terminal cancer now too, but it's impossible to get her to slow down. She still offers to have my daughter over for sleepovers, and she gets so annoyed when we try to help her the way she's helped us over the years
