What are the major developmental milestones for toddlers ages 1–3?
Milestones include walking, using simple words, following directions, early pretend play, feeding themselves, and expressing emotions.
At the HEED Coalition and The Basics Southcoast/RI, we believe that understanding developmental milestones is vital to supporting healthy growth from birth through early childhood. The early years are a period of rapid brain development, and paying attention to how children grow, move, communicate, and interact helps caregivers respond with intention and care.
Developmental milestones offer a general framework for understanding patterns of growth across areas such as language, motor skills, social-emotional development, and problem-solving. They are not a measure of perfection or a timeline every child must follow, but a tool to help caregivers notice progress, celebrate strengths, and identify when additional support may be helpful.
The resources in this section of the Birth to Five Resource Guide are provided to offer guidance, clarity, and reassurance as you learn about typical developmental milestones and what they may look like at different ages. Our hope is that these tools empower caregivers to observe with confidence, ask informed questions, and partner effectively with professionals when concerns arise.
These materials are informational in nature and are not intended to replace developmental screening, evaluation, or individualized guidance from your pediatrician, early intervention specialist, or other licensed clinical provider. If you have questions or concerns about a child’s development, a qualified professional can help assess needs and recommend appropriate support.
Children grow in many ways and at many paces. We hope these resources serve as a steady reference as you support learning, growth, and connection during the critical years from birth to five.
Milestones include walking, using simple words, following directions, early pretend play, feeding themselves, and expressing emotions.
Many toddlers say a few words by 12–15 months and use two-word phrases by age 2, though normal variation is wide.
If your toddler is not walking by 18 months, talk with your pediatrician or contact Early Intervention.
Limited eye contact, no pointing, lack of interest in social play, or not speaking by age 2 may warrant further evaluation.
Talking, singing, reading, and labeling objects daily help build communication skills.
Use simple sentences, run, climb, follow 2-step directions, show early independence.
Proper sleep, nutrient-rich diets, and predictable routines support brain and physical growth.
Speak in longer sentences, pedal a tricycle, copy simple shapes, play cooperatively.
If milestones are delayed or inconsistent, EI offers free evaluations for children birth–3.
No — development varies greatly, and delays often relate to health, temperament, or environment, not parenting.
