If you've witnessed this, there is no need for me to explain. If you haven't, one of your kids will just inexplicably squat in front of their chest (especially at Prouspire Manor and Honeyside, in my experience), look down at it and start rubbing their hands all over the front and top of it, like they're looking for something or checking what's in it (Note: that was the least disturbing anology I could think up for describing how this appears...), and 50% of the time it looks like their hands actually go into it (which is just a glitch...i know, I know--
shocking!). Oddly enough, they usually do it for exactly 10 in-game minutes or so, too (and oddly enough, I actually know that...).
What on earth are they supposed to be doing to it, or, just doing in general?? It's quite creepy for how benign the whole thing is.
Oh, and speaking of creepy, I noticed that when she plays with a doll, Sissel has her face about 190% closer to the doll than the other girls. No, that doesn't make a seriously freaky animation look even more like baby-eating. No siree.
