This is just my experience, whether its different for others I don't know. With thirst enabled while running "Babies and Children", babies cannot be given fluids until they either die or collapse. I tried disabling thirst in the experimental features and restarted the game to try and prevent their deaths, but they are now permanently affected by severe dehydration. I'm hoping they won't die and am going to try waiting until they're old enough to walk to re-enable thirst so they can get a drink. Sadly, given the lack of updates recently to "Babies and Children" it wouldn't make any sense to request a compatibility patch with it. What I would like to request though, potentially for other people with incompatible mods causing problems in their game, that the thirst, hygiene, or toilet-related moodlets and related illnesses could be removed from pawns during the restart when disabling features in the mod settings.
