ELI5: As growing pains are a thing in adolescents, with bone, joint and muscle aches, why isn’t that pain also constantly present for infants and toddlers who are growing at a much faster rate with their bodies subject to greater developmental stresses?

Babies and toddlers have the same growing pains for both their body and their developing minds.

Their perception of the pain may be different from when they are older. In general, they will be more fussy and easily irritated, sleep and eat poorly, or just cry for no reason. For some babies and their unfortunate parents, these symptoms are not too different from the everyday experience.
