Yes!
My DH and I split up when I was pregnant and I raised DS on my own for three years before we got back together. DH was happy to take my lead when we weren't together and now that we are, he has his own parenting style.. It's not wildly varying from mine, but the family dynamic is different. I'm bad cop to his good cop usually!
He also works away through the week which means re-adjustment to being a family of three at weekends.
We've just had another DC so it will be interesting to see how the dynamic changes again!
