Pediatric Growth &
Development Milestones
Ages 1 Month to 5 Years (Cognitive,
Motor, Social, Language, Reflexes)
The Ultimate Nursing Cheat Sheet
,INTRODUCTION
Pediatric nursing is challenging because:
• Interventions are weight-based
• Assessment depends on developmental milestones
• Early detection of delays = improved outcomes
• Different age groups require different communication, toys, safety, and
nutrition approaches
This guide provides a complete milestone chart used for:
• Nursing exams
• Clinical rotations
• Pediatric checkups
• Growth monitoring
• Developmental screening tools (Denver II, CDC guidelines)
REFLEXES — Quick Summary
All infants are born with primitive reflexes. Knowing when they disappear is
essential.
Reflex Appears Disappears Notes
Moro (Startle) Birth 4–6 months Sudden arm extension, then flexion
Rooting Birth 4 months Turns head toward cheek stimulus
Sucking Birth 4 months Enables feeding
Palmar Grasp Birth 5–6 months Infant grasps finger
Plantar Grasp Birth 9–12 months Toes curl around finger
Babinski Birth 12 months Toes fan out when foot stroked
, Reflex Appears Disappears Notes
Tonic Neck (Fencer’s) Birth 5–7 months One arm stretches outward
Stepping Birth 1–2 months Walking motions when held upright
