This is essentially what the big tech companies do with their onsite daycare. They have adults who get hired just to watch the kids, and you can pop in and out as your schedule permits.
It's hard to get work done when there are kids in the work area, so I can see why most companies don't encourage this. Especially since some people don't like kids.
Another even better solution is a remote workforce. Then only you have to deal with the distractions of your kid, except during meetings. As long as you can find something to do with the kid, or people are ok with kids on the conference call, it works out.
My employees are used to seeing my kid pop into the frame during video calls, and it's not really a problem.
The majority of my office is BL2 Lab space, people who bring their kids in are being incredibly irresponsible. The other aspect is a lot of people who would benefit from workplace daycare don't work in white-collar office spaces. Finally segregating people who don't enjoy distractions at work seems very rude, I like kids but I am overly cautious around them, if someone brought their kid into work I'd be more focused on the kid not killing him/herself than my job.
