My eldest is now 22yo and I was a very young mum who didn't really make rules for myself, because, really, I didn't really know what the social 'norms' where wrt to parenting. I just did whatever felt right (and that included bfing, co-sleeping, baby-wearing, but didn't realise they were gentle parenting methods then!). And as time went on, and I had other kids, the experience I had with my first taught me that making hard and fast rules were often a bad idea. But there were a few 'wishlist' things that i wanted for my kids:

Cloth nappies: yes, I bought some when Charlie was born. But I got lazy, and my empathy for the environment, and my passion for cute bums went the way of my feelings for laundry in general - it died a quick death.

Reading to my son every night: My XH did that in the end, and still does. When he's with mummy though, he has a choice - either you get to sleep in my bed, or I read you a story and you sleep in your own bed. He choses my bed every time.

Putting him in baby swimming/doing all these wonderful 'bonding' things together as mummy and baby: I didn't do this with my older kids due to lack of disposable income, but wanted to with my youngest. But he woke every two hours until he was 11 months old. I eventually was just happy not to keel over from sleep deprivation.

Attending school stuff/enrolling him in organised sport: When I went back to work, being there for him at school stuff was an exercise in futility. And turns out, I'm a really crap soccer mum.

No video games: except, when I'm cooking/cleaning/working/socialising/on the net/showering/resting, it's the perfect babysitter. And in the case of my older kids, the perfect way to stop them being sullen teenagers that drive me crazy. I try to regulate it, but don't always succeed.

I am more accepting of my shortfalls now when it comes to individual 'wishlist' items like this now. I'm more hard on myself about the parenting ideals that make a long term difference, such as being consistent, showing them I love them even if I don't always like what they do, being a good example and teaching them other good life lessons. One of those lessons, btw, is that I'm not perfect, but they don't have to be too to be awesome!
