Autism Spectrum Disorder (ASD) affects how a person communicates, interacts, and experiences the world. It typically appears in early childhood, and while every child is different, recognizing the early signs of autism can make a profound difference in a child’s development. The earlier autism is identified, the sooner intervention can begin, and early support can have lifelong benefits.
What to look for in toddlers (16 to 30 months) based on the Modified Checklist for Autism in Toddlers, Revised (M-CHAT)
Communication & Connection
Doesn’t respond to their name when you call them
Rarely points to show interest (like pointing at an airplane or dog)
Doesn’t use gestures like waving goodbye or shaking their head
Doesn’t bring things to you to show or share, like a toy or drawing
Doesn’t look where you’re pointing—they don’t “follow your gaze”
Seems more focused on objects than people
Doesn’t make eye contact often
Play & Imagination
Doesn’t engage in pretend play, like feeding a doll or pretending to talk on the phone
Shows little interest in playing with others, especially kids their age
Prefers to do things their own way, and may resist social games like peek-a-boo
Uses toys in unusual or repetitive ways (like spinning wheels or lining things up)
Repetition & Routines
Repeats the same actions or movements over and over (hand-flapping, spinning, rocking)
Repeats words or phrases without seeming to understand them (called “echolalia”)
Gets very upset with minor changes in routine or environment
Sensory Sensitivities
Seems unusually sensitive to sound, touch, lights, or textures (may cover ears, avoid hugs, or react strongly to certain fabrics or noises)
You Know Your Child Best
You’re not overreacting by asking questions. The earlier a child gets support, the more they can grow, learn, and connect. You’re doing something amazing just by paying attention.
