Daily weights


Weighing your child each day is an important part of the care the St. Jude staff provides.

Weight changes, especially in children, can occur quickly. Treatments and medicines used to fight disease can affect your child’s weight in just a short time.

Knowing your child’s weight helps staff members make safe and effective treatment choices.

  • Doctors and pharmacists use your child’s weight to help decide how much of a certain medicine to order.
  • Nurses and doctors use a daily weight to decide if your child needs to increase or decrease fluids, either by mouth or by vein.

The staff will measure your child’s weight before most clinic visits and any time the child is admitted as an inpatient. Doctors and other staff members often decide medicine doses and fluid needs early in the morning. So when your child is an inpatient, a staff member will weigh the child while taking the 8 a.m. vital signs, every day.


To learn more about why your child must be weighed every day, please talk to your nurse or doctor.
