Yes!
Complications over parents when you have kids, complications over arrangements, childcare, logistics. Complications about work - and although work is impossible with kids, it is because you have kids (and attendant need for roof, food etc etc) that you can't just pack it allin, live on your wits and see if you could take on a new direction. Working to maintain 'partner time', managing people's need to be involved with children - this last birthday w/e of DS's nearly did me in with the number of visitors we had (oh I sound so ungrateful - i'm not, we;re blessed with a wonderful circle of lovely people).
And everything is so sticky and cluttered.
