I don't know about age rules, but I do recall learning that children ages 2 and older were required to walk independently, without holding on to a grownup's hand (and certainly, not being carried). I learned this when I was writing my story, "Ellis Island Hanukkah," and researching the reopening of the immigration center at Ellis Island in 1900, when the new, red brick fireproof Main building opened (after the previous one - burned down). Guess what? Opening day was during Hanukkah!
