The 3-3-3 Rule for toddlers (and kids/adults) is a simple grounding technique to calm anxiety by engaging the senses: name 3 things you see, identify 3 sounds you hear, and move 3 parts of your body (like fingers, toes, head) to refocus on the present moment and away from stressful thoughts.

ADHD in a 3-year-old looks like extreme, persistent inattention (daydreaming, not listening, losing interest quickly), hyperactivity (constant running, climbing, fidgeting, excessive talking), and impulsivity (blurting out, interrupting, difficulty waiting, aggression, dangerous risk-taking), beyond typical toddler energy, causing significant trouble at home and daycare, marked by intense tantrums and difficulty with transitions and rules.

When to worry about toddler height?

We would like to see children with short stature if their height is below the third percentile (with normal parents' heights), if their growth velocity is slow (less than 4 cm per year) or if their height is greater than or equal to 3 standard deviations below expected height based on mid-parental height.

Signs your toddler is likely not autistic include strong social connection (eye contact, seeking comfort), varied imaginative play (pretend play, playing with others), flexible routines, clear communication (responding to name, using gestures like pointing/waving), emotional expression (empathy, showing affection), and broad interests with tolerance for mild sensory differences like scratchy tags, indicating typical development in social-emotional and communication areas.

What is a red flag for autism in toddlers?

Red flags for autism in toddlers involve challenges with social communication (like avoiding eye contact, not responding to their name, limited sharing of interests) and repetitive behaviors (like hand-flapping, lining up toys, getting stuck on routines) or unusual sensory reactions (over- or under-reacting to sounds/textures), often accompanied by speech delays or regression, and intense tantrums or difficulty with change. Recognizing these signs warrants a check-in with a doctor for early screening and support.

The "autism mirror test" usually refers to the Mirror Self-Recognition (MSR) test, which assesses if someone recognizes their reflection, but studies show autistic individuals often pass it, though sometimes with developmental delay or different engagement, suggesting self-recognition isn't the core issue; instead, research focuses on the Mirror Neuron System (MNS) and mirroring of facial expressions, where autistic individuals might show reduced activity or different responses, leading to social deficits, though findings are complex, suggesting modified brain responses rather than a completely broken mirror system. 

What can stunt a child's growth?

A child's growth can be stunted by poor nutrition (lack of protein, calories, zinc), chronic illnesses (heart, kidney, lung, digestive issues), hormonal problems (growth hormone, thyroid), severe stress or neglect, infections, genetic syndromes, and sometimes lack of sleep or poor sanitation, all hindering the body's ability to develop to its full potential.
