However, vaccination coverage among U.S. kindergartners has decreased from 95.2% during the 2019–2020 school year to 92.4% in the 2025–2026 school year, leaving approximately 280,000 kindergartners at risk during the 2025–2026 school year.
Professional Corner: Pediatricians Call for New Border Protections, AMA Awards $1 Million in Grants and More
The AHA opens its health tech competition, AMA awards $1 million in community grants, and pediatricians call for stronger protections for children at the US border.
Research of the Day
Naturalistic Developmental Behavioral Interventions Before Age 2: RCT
This RCT provided Naturalistic Developmental Behavioral Interventions (NDBI) to infants showing early autism markers at 12-18 months. Early intervention significantly improved social communication outcomes at age 3.
Key findings: (1) 40% of intervention group no longer met ASD criteria at age 3; (2) Greater gains when started before 15 months; (3) Parent-mediated strategies effective when coached by professionals.
Refer promptly when developmental concerns arise—don't wait for definitive diagnosis. Early intervention can meaningfully change trajectories. Coach parents to implement strategies in daily routines.
Popular Beliefs
Cracking knuckles causes arthritis
What the evidence shows: Studies comparing habitual knuckle-crackers to non-crackers found no increased arthritis risk. The cracking sound is from gas bubble release in synovial fluid. The main consequence may be reduced grip strength and annoyed family members.
Shaving makes hair grow back thicker and darker
What the evidence shows: Shaving removes hair at the skin surface, leaving a blunt tip that may feel coarser as it grows out. However, it does not affect hair thickness, color, or growth rate. This is an optical illusion from the blunt vs. tapered hair shaft.
Warm milk helps children sleep
What the evidence shows: While milk contains tryptophan (a sleep-promoting amino acid), the amount is modest. Any sleep benefit likely comes from the comforting ritual and warmth rather than pharmacologic effect. A consistent bedtime routine matters more than any single component.
Behaviors
Early Pet Exposure and Immune Development: Birth Cohort Study
This birth cohort followed 1,200 children from birth to age 5, comparing immune development and allergy rates in homes with and without pets. Early pet exposure was associated with reduced allergy risk and altered gut microbiome.
Key findings: (1) 30% lower allergic sensitization with dog exposure in first year; (2) Cat exposure showed similar but smaller effects; (3) Microbiome diversity increased in pet-exposed children.
Reassure families that pet exposure during infancy may actually protect against allergies. For families without pets, don't specifically recommend getting one, but dispel the myth that pets must be removed to prevent allergies.
Genetics
CFTR Modulator Therapy in Young Children: Expansion to Additional Mutations
New clinical trial data supports expanding CFTR modulator therapy to children as young as 1 year with various CFTR mutations. Early treatment initiation shows benefits in lung function preservation and nutritional status, with excellent safety profile.
Key findings: (1) 85% of CF patients now eligible for modulator therapy; (2) Early treatment prevents rather than reverses lung damage; (3) Growth parameters improved in treated toddlers.
Refer CF patients promptly for genetic classification and modulator eligibility assessment. The treatment landscape has transformed—many children can now expect near-normal life expectancy with appropriate therapy.
