Kids and Hormones

SPROUTING, CHANGING, GROWING

Voice changes. Acne. Raging hormones. At some point, every little boy and girl grows up and into adulthood. The stage of life when this is most present is puberty. What’s the best way to explain what your child is going through? Less is usually best. “Normally, if kids ask questions, they don’t need detailed answers,” says Dr. Reh. “Answer just the question they ask. Keep it very simple; tell them it’s a normal process.” Parents should also be prepared to answer questions, again in simple terms, about what’s happening with the opposite sex.

FOR GIRLS ONLY

The first signs of puberty are either breast buds or hair growth in the private area, says Dr. Reh. In addition, girls will experience a buildup of fat in the breasts and around the hips, then the arms, legs, hands and feet will also grow taller early in puberty. “Later, around stage four of puberty, menstruation will begin,” says Dr. Reh.

FOR BOYS ONLY

“For boys, the earliest beginning signs of puberty should not start before age nine and they can be as late as ages 13 to 14,” says Dr. Reh. “The first sign for boys is actually testicular enlargement.” As time goes on, boys will begin to experience increased body hair and their voices will crack and become deeper. The growth spurt for boys is in the later stages of puberty.

LATE BLOOMER

Some children will experience delayed puberty. “It’s actually the most common reason for being shorter than your friends,” says Dr. Reh. “And it tends to be a benign [non-threatening] process.” If you have concerns about early or late puberty development, talk to your child’s pediatrician.

FAST FACTS

  • Ages when puberty generally starts for girls: 8-13 Years Old
  • Ages when boys experience a growth spurt: 10-16 Years Old
  • Percentage of boys that develop temporary breast tissue during puberty: 50%
