Among the Sleep is the name.

They say about a year to come out, however I guess if it comes out I can chances are add it to the list of games I've played because of this part of my personality.
Bio-Miracle Bokutte Upa
Waxworks-one of the bosses
Light Fantasy 2 (wish the translation patch wasn't abandoned)
Henry Hatsworth and the Puzzling Adventure
Earthbound, Mother in general (just the feelings really, although Earthbound has something close to AR in it, as such I would like to see more Mother AR)
A boy and his Blob, Shantae (I have no idea how this happened)
Maximo: Ghosts to Glory. Continuing on with the Ghosts n' Goblins series in general really just to see if they do more AR, 1st time I played SGNG way back when I ended up being turned into a baby in world 2. I think of it as a part of a trigger.
Legend of Zelda: Oracle of Ages (or at least wanting more Zelda AR, it certainly helps me like Majora's Mask more as well)
Yoshi's Island, Touch and go, DS
Mortal Kombat in general (didn't really look into it more until a computer turned me into a baby at an arcade back in the days of MK2)
Imagine Party Babies (even then I wouldn't recommend this sack of ****)
Change Match-Flash game
Old Man Baby-Flash game
My Baby Boy (more BS)
Baby Jo in going home (actually not that bad, still tons of flaws though)
Various rom hacks (Super Baby Brothers...don't get it)
Dragon's Lair Trilogy (in this case, Space Ace)
Pretty sure I'm missing some or forgot to add them to the list, but still. Lots of babies in games.
