First one just turned two. I waited until I was 40 to have a child for this reason. I wasn't ready. I didn't trust my relationships with my demons. I didn't want to burden her with my shit. Still got a whole lotta unbecoming to do, but having her around definitely keeps that flame lit under my ass. There's a wonderful buddhist mindset of looking at difficulties or challenging situations and labeling them as "this is my guru" and that's what I've done with her. She's holding up a very untarnished mirror to my behavior and lifestyle 24/7.
Edit: It's worth noting that my perfectionism turned on fatherhood means I'm a motherfucker of a dad. The key is to use that energy wisely, don't let it get out of control like it did with me. That's a really special gift we both have. Just learn to dance with it.
