The 5 days normal infant lifespan is hilariously bad
I would say that infants is probably the most complex out of all the lifespans and they decided that 5 days was a good amount of time to anything. Infants have LOT of milestone and stuff to unlock. Trying different foods requiring sitting up, which is a milestone that is unlocked after a lot of tummy time. Tummy time takes a lot of time since it's not a continuous activity, it's something that requires you having to spam, and if both parents work outside the home, then it's not happening.. Infants want to sleep every hour which also takes up time. With infants, on top of trying to unlock milestones the ability to try foods, they also have a practice standing and crawling, the latter in which is required to be able to read to them.
The point is, that 5 days to do anything in that lifespan is just bad. I have a mod that sets my infant's lifespan to 15 days. 15 day is long, and I was able to unlock all the food preferences and a lot of milestones but not the crawling, which I'm still working on before she ages up in one day. It can still be a grind. I'm aware that people can turn aging off and that long lifespan is a thing, but normal lifespans with aging on, you'll be lucky enough to get the infant to clap before they are suddenly aging up into a toddler.
If you're a completelist, this stage will drive you mad on normal lifespan with aging on.
