One useful thing to remember is that our heads grow a lot less relative to our bodies. Our bodies get like.... I dunno, 7-10 times taller (?), but our heads only get 2-ish times taller through our lives. I grabbed this google image of a "mom and baby":

You can see that mom's head is only a little bit larger than the baby's. So when drawing kids I usually give them pretty huge heads relative to their bodies, and heads only a little bit smaller than the adult's. I usually do something like eyeball the adult --> figure out the child's head size relative to adult --> give the child a body based on the size of that head.
Speaking of children - did some work on Engram today!
