Understanding Your Child's Development
This checklist is organized by age group across five developmental domains. Milestones represent typical age ranges, not strict deadlines. Children develop in sequence but timing varies. Check off skills your child has achieved. Concerns? Speak with your pediatrician.

Feeding: Feeds self finger foods independently, drinks from straw (9-12 months), beginning spoon use with much spilling, chews soft solids with up-down jaw movement.
12-18 Months: Walking & Vocabulary Explosion
Gross Motor: Walks independently (12-18 months), walks upstairs with hand held, runs (hurried walk; may fall), kicks a ball forward.
Fine Motor: Stacks 2 blocks (by 14 months) to 6 blocks (by 18 months), scribbles with a crayon making clear marks, throws a small ball, points with index finger (12-16 months).
Visual Motor: Imitates strokes after watching a model, places shapes into simple shape sorter, matches identical objects, completes simple 2-knob puzzle.
Language: 5-20 words, points to request AND to share or comment, identifies 2-3 body parts on self or doll, beginning to name familiar people and objects.
Feeding: Uses spoon with significant spilling, eats most soft family foods, uses open cup with assistance, emerging independence at mealtimes.
18-24 Months: Climbing & Two-Word Phrases
Gross Motor: Runs fairly well; walks backward, walks downstairs with one hand held, squats in play without losing balance, climbs onto furniture.
Fine Motor: Stacks 6 small blocks (22-24 months), holds crayon with thumb and fingers (23-25 months), turns book pages one at a time (21-24 months), imitates a vertical stroke.
Visual Motor: Imitates vertical and circular scribbles, completes a 2-3 piece puzzle, matches colors and basic shapes, simple pretend play with objects.
Language: 50 or more words, beginning 2-word combinations ("more milk," "daddy go"), names pictures in books, follows 2-step commands.
Feeding: Uses spoon with less spillage (20 months), eats more varied textures, transitioning to open cup, good straw drinking established.
24-30 Months: Jumping & Complex Play
Gross Motor: Jumps with both feet off the ground, walks up and down stairs (both feet per step, with rail), climbs playground equipment, rides a push toy without pedals.
Fine Motor: Copies a circle (25-36 months), strings 1-inch beads (23-25 months), folds paper in half (24-30 months), imitates a 4-block train (27 months).
Visual Motor: Imitates horizontal stroke and circular scribble, completes a 4-5 piece puzzle, sorts objects by shape or color, matches colors consistently.
Language: 200 or more words, 2-3 word phrases consistently, asks "what's that?", uses words more than gestures to communicate.
Feeding: Pours from a small container (32 months), uses a fork (30 months), eats most family foods with minor modifications, feeding largely self-directed.
30-36 Months: Balancing & Complex Sentences
Gross Motor: Climbs stairs alternating feet (holding rail), balances on one foot for 2-3 seconds, rides a tricycle independently, throws a ball overhand with direction.
Fine Motor: Copies a cross (+), makes continuous cuts across paper with scissors, draws a simple person with 2 or more body parts, stacks 9 small blocks (32-36 months).
Visual Motor: Copies a circle independently, completes a 6-8 piece puzzle, draws simple recognizable shapes, sorts by multiple attributes.
Language: 300 or more words; 3-4 word sentences, asks why and how questions, understood by unfamiliar listeners 75%+ of the time, uses pronouns: I, me, you, he, she.
Feeding: Self-feeds complete meals with spoon and fork, drinks well from an open cup, food jags and strong preferences are normal and expected, beginning to spread with a butter knife.
Key Note on Solid Foods
Signs of readiness for solid foods include: sitting with minimal support, bringing hands to mouth, good head and neck control, showing interest in food when others eat, and tongue thrust fading. Some families choose to begin with purees; others use a baby-led approach with soft table foods. Both are valid. Either way, food preparation and texture matter. Consult your pediatrician for individualized guidance.
