Posture is the body position your child assumes while standing or sitting. If your child has poor posture, his head may droop forward, his neck may jut out, and his back may be hunched over. If your child has good posture, his neck, back and head should be straight and relaxed. Poor posture may be a result of bad habits, like slouching and slumping over. In some cases, bad posture may be the result of a more serious illness or disease, like scoliosis.
Consult your child's doctor to rule out scoliosis. Scoliosis is a curvature of the spine that can be treated with a back brace, states the Mayo Clinic. If your child has scoliosis, the spine will curve, giving your child's posture a slouched appearance no matter how straight she sits up.
Sign up your child for dance and movement classes, suggests physical therapist, Sharon DeCelle. As your child becomes more comfortable with moving his body, he will become more agile and flexible, making it easier to break bad habits and to stand up straight naturally.
Purchase a child-sized chair and desk that are the right height for your child. This way, your child will not have to assume slouching positions while trying to read or do her homework.
Prop your child up against the back of the couch or the wall when watching TV or playing games on the floor. Instruct your child to rest his entire back and head against the couch or wall as he keeps his neck straight.
Instruct your child to get up and stretch or run around the room after about every half hour of sitting. Allow your child to touch his toes or reach his hands up in the air if he's starting to slip back into that slouched position.
Stretch with your child after waking up each morning.
In cases of severe scoliosis, the spine may put pressure on the heart or lungs, causing heart irregularities and difficulty breathing.
