My 13 Year Old’s Physical Behaviors/
Characteristics
■ The 13-year-old boy I observed is in eighth grade
and fits the normal example of physical
development. He is somewhat taller than most of
the boys and girls in his classes. Furthermore, there
are a few things that have not struck him yet like his
voice has not changed. Generally speaking, he is by
all accounts developing ordinary physical qualities
for a boy his age.
Physical Development Recommendations
■ Adolescents often times need their privacy when they are going
through physical changes and adults should be able to
understand and give them their privacy/ personal space (Medline,
2017).
■ Parents need to remember that it is natural/normal for their
adolescent to be interested in body changes and sexual topics. So
it is important for parents to be open and willing to answer any
questions their adolescent may have about the physical changes
they are going through (Medline, 2017).
■ Adolescents tend to be self-conscious about their bodies physical
changes and the way they look is important to them. So
adolescents should not be criticized nor compared to others.
(Medline, 2017).
■ Adolescents should be allowed to have their own time by hanging
out with friends and peers in order to form their own identity. This
means it is normal for adolescents to separate from their parents
(Medline, 2017).
