Yes all of the above. We hadn't a clue how to do things when we started but we sort of muddled through. Trying to set a good example helps I'm sure.
We have stuck together (as did both our sets of parents) so I suppose there were male role models there. We have tried to be 'signposts to God' while - with St Paul - thinking of ourselves as 'chief of sinners'
Not going to 'boast' but things have worked out very well for whatever reason; my feeling is that DCs are like assorted plants; you don't know what variety of seeds they are but you just provide the soil and nourishment for them to grow into the plants they have the potential to become.
Two anecdotes:
When DS1 was about 5 I did something 'wrong' - can't remember what. He was taken aback. I then confessed 'yes that was wrong; grownups sometimes do things wrong or make mistakes'. 'But if you know enough to recognise wrong actions, then it's your responsibility to make sure you don't copy the wrong actions.' I could almost see the little light bulb of understanding coming on! He's now in a good job with 2DCs, and a lay preacher!
DS2 was a terror: wrecked everything; filled the bath then emptied it all on the floor (new ceiling needed downstairs), no idea it was wrong - it was just fun; pulled the TV off a high shelf by the cable and it nearly fell on him. Always asking 'why'? then yes, but why ....? Quite mischievous and the usual sibling wars. But I was going through management training / personality analysis at the time and could see the underlying traits. (Also - let's admit it, saw a younger version of me!) So I felt that so long as he could be mischievous without being malevolent, all would be OK. He followed me to Cambridge, did science then theology, and as a Philosophy / RE teacher is an intellectual match for the trickiest sixth-former.
Proud of them both, of course. And very thankful.
DW's part (apart from doing all the million things mums do): prayed regularly for them all.
