Oops - posted too soon.
Our parents met for crisis talks to "clear the air" (why? They hadn't fallen out!) and I had my mum telling me his mum was worried she would see less of dd - the only person who would cause that is her, she hardly offers to have her often and often declines to have her when I am occasionally stuck for childcare.
It seems our parents were far more upset about it than we actually were - it has been very amicable so far.
We also had "well won't you think about dd?!" As though we had not given that a thought at all when making our decision to split. 
Organising Xmas was a big drama, when in fact we pretty much did what we did every year, dd spent half the day at his parents, half the day at mine, except we didn't go together as a couple.
I did point out to my mum that she was actually making it far harder than it needed to be and she threw a bit hissy fit and made it all about her, you would have thought it was her going through a break-up, not me. I don't feel I really have any emotional support from anyone, there is very much a "you made your bed now lie in it" attitude.
Friends have been very good about it - though I am quite a private person and have not announced it to everyone yet.
