A. hi dear Growing pains are cramping, achy muscle pains that some preschoolers and preteens feel in both legs. The pain usually occurs in the late afternoon or evenings. But it may cause your child to wake up in the middle of the night. Growing pains usually start in early childhood, around age 3 or 4.
