I handle it just fine now, but I did lay some groundwork before kids to make sure my life was going to continue to be easy even with the added responsibility of parenting:

• Insignificant commute. I can leave my house and be at my desk at the office in about 10 minutes, even during rush hour, because the bike lanes still flow efficiently.
• Small home. I don't want to fuck around with house maintenance or even cleaning up around the house any more than is absolutely necessary, so I don't have excess rooms in the house and don't have big spaces. I also don't fuck with yard work so I have only a small patio with a few planters for a modest garden.
• Flexible career that I actually like. I have a decent chunk of work to do in any given week, but most of it can be done on my own schedule, so that I can start my day late or end my day early as needed, so long as I can find the time elsewhere to fill in as needed. This did take some work to find a career that I like and that actually complements my strengths (several complete resets in my 20's and 30's, including going to law school as an older student), and then advancing in that field long enough to where I just have credibility to get things done without other people supervising me. I do work more than 50 hours per week fairly regularly, but I largely do it on my terms.
• Money. My wife and I both earn more than average, and we were already rich before we had kids. That gave the flexibility to do things like take unpaid leave for each kid being born, paying for childcare when they were young, grabbing takeout on days when time is tight, etc.
• Social support network. We have some family nearby, and they can help in a pinch (and we in turn help them as necessary). Our neighborhood social group is amazing, with a lot of other parents and similarly aged kids who can provide the social and emotional support for navigating the very real challenges of parenting. We don't feel like we're doing things alone, and we have a village. Many of these relationships predate parenting, too, so in a sense we knew that we had that ecosystem of friends and family to continue to grow with (even if we wouldn't have been able to predict in advance exactly which friendships would thrive and which would wither after kids, we had the baseline to be able to be flexible with that).

There were tradeoffs, to be sure. We were older than average when we had kids, and that might translate into lower energy levels for each stage of childhood, and may eventually mean that we get to enjoy less overlapping time as adults. We live in a small place so we do need to basically leave the house regularly so that our kids don't get bored, and that's more of a challenge in the winter when outdoor spaces aren't all that pleasant. During COVID, while working 100% remotely, being close to the office wasn't all that much of a perk.

And we got lucky on other things. Our children are healthy and (mostly) well behaved, so we don't have to worry as much about a lot of things other parents have to deal with. We also really get along with our own parents, so there aren't challenging dynamics with the grandparents/in laws.
