Mostly, because it’s an instant way to find out if your kid is normal or not. For instance: today I googled “baby sucking on upper lip”– and voila, found a whole chat room about babies her age that suck at their upper, lower, or just making a fish face and sucking nothing at all. Whew. At least we’re not the only ones. Although it makes me feel a little odd, like why is she doing that? But since it was listed by people who didn’t also say their kids had drastic syndromes, I’m assuming she’s alright.. it’s a funny face, though!
