1. A toothless grin. Babies are just cute without teeth. But, if a full grown adult smiled at you and didn't have teeth, I think you'd be freaked out a little and you would probably wonder about their hygiene.
2. Farting out loud. Okay, it's not necessarily cute, but it's funny. Myla will just rip a loud one (sometimes with some bubbly poop along with it) out in public and there is no shame. This happens a lot in Relief Society, and the ladies in there just turn to look at her and laugh. If I, however, ripped one, I don't think the ladies would give me the same reaction.
3. Frowning and crying. Let's be honest, that little frown babies give before they cry is adorable. On adults, eh, not so much. Babies just don't have an ugly face when they cry. I, on the other hand, have an ugly face when I cry. As one of my friends and I used to joke around, we have "an ugly cry".
4. Drooling. I don't think drool is "cute", but it's at least acceptable for babies to drool. I don't think I'd be so attractive with dribbles going down my chin and onto my shirt.
5. Fat rolls. Don't you just want to squeeze those chubby cheeks? Don't you just want to chew on those chubby arms? I was talking about that guy over there. Oh, now you don't want to squeeze those chubby cheeks and chew on those chubby arms?
Yes, babies are just cute no matter what. Unless they had baby dentures.
