Just sort of around. It's really hard to actually catch a baby as it appears without camping out at a good spot for months on end, generally one has to find them later on, but they can be most anywhere sort of tucked away. Somebody anonymously invented a kind of golem that goes and listens for crying and brings the babies back to the nearest creche, that's done wonders for population stability now that it's not all hikers stumbling over infants tucked into hollow logs or whatever.
I mean, I'm kind of grossed out by the idea of babies being caused by sex in sapient creatures, but I'm trying to be open-minded here.
I guess there are advantages to that system. We get kind of used to it being a fact of nature that sometimes babies die of exposure and starvation alone in the woods, we can't find them all - there do seem to be new stork golems occasionally, somebody's still churning them out in batches, we just don't know who.
Our wilderness areas are safer, I guess? I don't go hiking much for obvious reasons but I'm pretty sure it's commoner to find a live baby than a dead one.
I can't think of any earthly reason I'd want a baby around. I don't think I could stand to have an apprentice younger than four and it'd have to be a precocious four. Some people like babies and take them off the hands of overloaded creches, but that's not common at all, usually it's creches up until the kid's ready to eat with utensils and not throw rocks indoors and learn something. Some kids don't even get apprenticed, they just stay in the creche until they feel like striking off on their own.
I found my creche way too crowded, honestly. Skipped out with the first servantmaking teacher who came by. People make friends! The well-organized creches make sure there's some adult responsible for giving any given kid individual attention!
I guess. Creches have perpetual problems getting enough people to work at them, the staff are usually really dedicated but most people have other things they want to be doing with their lives...
