Child Development by Age: Check Whether Your Child Is Growing and Developing on Track
Concerns about child development are common among parents. Regularly observing and monitoring your child’s developmental progress is important because it can help identify areas that may need additional support and guide age-appropriate health care, learning, and development.

Developmental Milestones from Birth to 5 Years
Child development involves several areas, including gross motor skills, fine motor and problem-solving skills, language understanding, communication, and social-emotional development. The following provides a general overview of developmental milestones. Each child develops at an individual pace, so these examples should not be used as strict deadlines.

  • 0-6 months: Babies gradually become more responsive to people and their surroundings. They develop increasing head control, begin rolling, respond to sounds and familiar voices, smile socially, and make early vocal sounds.
  • 6-12 months: Physical control and mobility continue to develop. Many babies learn to sit independently and move around by rolling, crawling, scooting, or other methods. They increasingly reach for and grasp objects and begin responding to familiar words, names, and simple communication.
  • 1-2 years: Many children begin walking independently, develop an increasing vocabulary, follow simple instructions, use gestures and words to communicate, and become more interested in interacting with people and their environment.
  • 2-3 years: Language and communication skills expand rapidly. Children may begin combining words into short phrases or sentences, ask more questions, imitate or draw simple lines and shapes, and become increasingly independent in everyday activities.
  • 3-5 years: Children generally become more coordinated and independent. Their language develops further, allowing them to hold conversations and tell simple stories. Social skills also progress as they learn to play with others, take turns, follow routines, and share with support.

Warning Signs That Should Be Discussed with a Doctor
Development varies from child to child. However, parents should consult a pediatrician if they notice significant concerns, loss of previously acquired skills, or persistent delays in developmental milestones. Examples that warrant further assessment include:

  • By around 6 months, rarely smiling, showing little social response, or having difficulty controlling the head.
  • By around 12 months, not responding to their name or familiar sounds, rarely using gestures such as pointing or waving, or showing significant difficulty with movement or communication.
  • By around 2 years, not using meaningful words or beginning to combine words, or having significant difficulty understanding or communicating with others.
  • At any age, losing language, movement, social, or other developmental skills that the child could previously perform.
