Dh and I work together very closely but as the years have gone by (oldest dc is seven now) its clear that left to our own devices he'd be much more relaxed about treats, food, bedtimes etc. Left to my own devices there'd be much less fun and more grumpiness despite the fact they'd always eat well and go to bed on time. I suppose I shouldn't be surprised as this does mirror our upbringings.
Have you been surprised by any differences you have and compromises made?
