  • AAP recommends insect repellents should be less than 30% DEET and used for infants 2 months old and older. Wash off skin with soap and water when done. Wash clothes before wearing again. Do not use combination DEET and sunscreen products. Apply permethrin for ticks to clothes, not to skin.
  • Use a sunscreen with an SPF of 30 or higher, reapplying every 2 hours, and avoid peak sun intensity of 10 am to 3 pm.


  • Says 1 to 3 words.
  • Uses “jargon” speech (makes sounds with changes in tone).

Other Helpful Notes:

  • Teething: Do not use ORAGEL® or similar numbing gels. The ingredients are known to cause a rare serious disorder called methemoglobinemia. Offer cool, soft teething rings or toys.
  • Brush any erupted teeth with a soft infant brush and a tiny dab of fluoride kid’s toothpaste.
  • Take your child for their first visit with a pediatric dentist.

Watch Out For:

  • Please contact your provider if your baby can’t stand with support, doesn’t point to things, doesn’t say “mama” or “dada”, or doesn’t learn gestures like waving or shaking head.
