I'm having this same issue. Not as badly as some, but it is noticeable. These are all sim children and a toddler that were born in game. They have never been aged up in CAS. The child boy seems relatively normal as far as I can tell, but the child girl has noticeably gained weight in her stomach and rear. Having her use a slimming potion keeps her torso the same but gave her skinny arms and legs. My toddler seems to have a different shaped body too, but I lack previous screenshots to show exactly how. He looks older? A longer torso I think. I think my infants are ok but that family is so chaotic with 2 infants, a toddler, 2 children and a dog I didn't look at their faces closely! Interestingly they seemed to change gradually? I swear the girl looked normal at first but got fatter. I quit without saving so cannot provide a save file at the moment.
EDIT: I have a couple of crafting mods and some custom farm animals, but all other cc is build/buy stuff.
