Learn the Signs. Act Early. (LTSAE) is a program of the U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC) that encourages parents of children ages birth to 5 years and providers who care for them to

  • Learn the signs of healthy development (developmental milestones);
  • Monitor every child’s early development; and
  • Act early on possible developmental concerns: talk with the doctor and ask for developmental screening.

The program offers parent-friendly milestone checklists, printable from the CDC website or accessible through a free app, that make developmental monitoring practical and easy.

Note: The materials provided by LTSAE are parent education and engagement tools that support developmental monitoring and help staff decide when to refer a child to other professionals for screening; they are not a replacement for developmental screening.
