I am fortunate to have had a great relationship with my parents, and I'm honestly able to say I wish I parented more like my mum than I do, but as I've got older I have realised there were some things she passed onto me that haven't benefited me so much, and that I want to avoid passing on to my kids
She always stressed the importance of being the peacemaker and compromising for the sake of an easier life - DF can have a very bad temper (as can my DH) and it's taken me a long time to be able to stand up that temper and to be firmer that, when it happens, it's his responsibility, not mine. I want my kids to see me standing up to his worst moments, because I don't want them to feel (as I did) that the person who shouts loudest and is angriest always gets their way. I find it very hard to do, but I have always felt glad after I've done it, even if the result is not satisfactory.
DM was also of the view 'Well, you have to choose kids or a high flying career, you can't have both', and I sometimes wonder if I set my sights a bit low because of that career wise - although that said, I can't think of anything high flying/earning that I would be suited to anyway. I chose a career that I do really love and I knew would allow flexibility (and is quite female-led) but it's not really a route to megabucks or big responsibility. That said, now that I think careers are longer (I'm sure as heck going to have to work a long time to get a decent pension) there is more leeway and now my kids are older I am looking to step things up, and my early 40s still feels like plenty of time to do that. I think I will tell my kids (both DS and DD) that if they want to have family they may want to plan ahead to get the best balance - not obsessively, but when they come to the end of their education to think about whether they're likely to have a family, what's important to them and how a career and kids might fit together and how they can build a career and financial situation so they are ready when they want to be. Rather than, as I heard a colleague once say, taking the attitude 'I'll think about kids when I'm 30' - cos that's a bit late if you haven't got your shit together, IMO. As I said, that's for both kids, not just DD.
