Oral Method – Recommended for children 4 years and older
Place the probe tip under the tongue and close the mouth. Instruct children not to bite down on the tip.
Rectal Method – Commonly used for babies and young children
For easier insertion, position the baby on their back and have their legs form a 90-degree (L-shaped) angle. Try placing the child on your lap with their legs down. Gently insert the probe tip no more than a ½ inch (1.3 cm) into the rectum. Do not force probe tip into the rectum if you encounter resistance. Note: Use a lubricated thermometer cover.
Underarm Method – Recommended for all ages
Wipe the underarm with a dry towel or cloth. The probe tip must touch the skin. Place the probe tip in the center of the underarm and lower arm against body.
