A Chozo chick sleeping on its mother's chest. Very sleepy from a long, busy day of staring inquisitively at strangers and peeping.
I have many thoughts about Chozo children, the foremost being "they're soft and ungodly cute." They hatch cold, wet and angry, then develop plumage over the first few weeks of their lives: first a soft layer of down, then big bird feathers later on. They have a surprisingly powerful grip, which they use to cling to their parents: the neck, chest, and shoulders are common places one might expect to see big, round baby Chozo eyes peeking out from.
Hatchlings generally don't need their parents to carry them in their arms, as the babies are strong enough to hold on for dear life. Mom and dad have many feathers and a thick layer of down to dig into. The extra skin on their necks also makes it easier for the little ones to hang on. There's no need to use a harness unless your baby has some degenerative muscle or nerve condition that weakens their grip.
As a chick grows older and its limbs become stronger, it may move while hitching a ride. You could start an outing with your baby on the back of your neck, only for her to make the pilgrimage to your chest later on in the day.
Chozo chicks also make many noises: peeps, chirps, cooing, annoyed grunts, little hissy growls... they're very expressive, and they like to talk when they're not absorbing information from their environment like little sponges. They also try to imitate their parent's voices: a father who sings to his child while putting them down for the evening may find junior affectionately chirping a few notes back at him the next afternoon during play. This not only shows that the child's working memory is developing, it also gives papa bird warm fuzzy feelings.
