Beautiful child-level appearance

What do children like the appearance of their caretakers to be? Just like teens and grownups are beauty preferring what is beautiful to children? Is there anything about the lower third of an adult sized body that could be optimized to benefit children's aesthetic experience? That’s the part they see a lot.

I think that although some of this is learned, I think there is likely a large innate and even genetic component. I think I read that babies turn away from people with beards. So, what do they like and turn towards?

I am imagining a velvet flannel in bright colors or pastels, perhaps with fiber optic light spots. Perhaps there could be patches that say things like "hug" or "hungry" or an image of the family pet, on them and somehow the child pressing on the patch would alert the adult to the hug preference.

Adult shoes that children prefer viewing could be another area of this.

My perception is that fashion has some re-runs yet values new things. As far as I know what kids look at,and like, on adults is new fashion territory.
