Biodegradable wet wipes are a thing. They are a bit rougher but not bad.

Biodegradable nappies/diapers exist too but they are awful. Similar to try cloth or reusable (with a changeable lining). Awful.

We use reusable nappies for our toddler, and the washing machine is powered by solar so I only really need to feel bad about any excessive water use. But then we still have to use disposables when they’re at their nursery for a few days a week, or the staff don’t smell anything and they get bad rashes we spend all week dealing with. At the very least though the nursery deals with nappies as a specific form of waste that they process separately, though I’m not sure to what end.

Wet wipes are a ridiculous waste.

Bidets are very accessible.

I would expand that and say small kids in general are super wasteful. They consume a lot of resources, produce a lot of trash (and noise) and are a significant source of stress and sleep deprivation, both of which are suspected of causing cancer. 😅
