When Can a Child Go Into A Pool?

Patient Presentation
A pediatrician was at an outdoor community swimming pool and noted 2 very young infants being played with in the pool. Both were being submerged up to their trunks and had sun hats on. Knowing that the pool contained various chemicals and that there was the possibility of water-borne infectious disease, he wondered at what age a child could go into a pool. He later looked up several references from medical professional societies and national non-profit agencies. He did not find a specific answer, but did learn more information to better advise parents.

Water safety is clearly important for all ages. Drowning was the second leading cause of unintentional injury death in US children from 1-19 years between 2000-2006. Non-fatal drowning victims usually do well, but 5-10% have severe neurological damage. The highest rate of drowning is in 0-4 year olds, with half of the drowning occurring in swimming pools. Infants < 1 year have a high rate of drowning in bathtubs and large buckets of water. To prevent drowning, experts generally recommend "layers of protection" including:

  • Adult supervision – a designated adult supervisor who is not distracted by other activities such as sun bathing, reading, or talking with other adults
  • Pool fencing – separate 4-sided fencing isolating the pool from other structures including a house
  • Pool covers – always totally removed during use and replaced after use
  • Pool alarms
  • Lifeguards
  • CPR training
  • Swimming instruction and water-survival skills
  • Personal flotation devices – see “What Type of Life Jacket Should He Wear”

The American Academy of Pediatrics recommends that “[a]ll children should eventually learn to swim.”
The AAP supports swimming lessons for most children > 4 years of age. Some children may not be ready for various reasons until later than this age.
For children < 1 year the AAP recommends these experiences be individualized. They state "…the current evidence is insufficient to support a recommendation that all 1- to 4-year-old children receive swimming lessons."

Learning Point
Potential concerns for infants and young children regarding pools and other recreational water include:

  • Neonatal immunity
  • Infectious water-borne agents especially gastrointestinal tract infections – see the CDC’s Alphabetical Index of Water-related Health Data
  • Skin problems including dermatitis and sunburn
  • Acute respiratory illnesses including potential increased risk of asthma and bronchitis secondary to chlorination byproduct exposure
  • Hypothermia – secondary to cool/cold water and air exposure
  • Hyperthermia – secondary to high water temperature exposure in spas and hot tubs
  • Hyponatremia – secondary to water ingestion

Questions for Further Discussion
1. What are the concerns about pool drain entrapment?
2. What are the differences in potential problems for fresh water versus salt water drowning?
