The 18-month visit often includes a developmental screening, and your pediatrician may ask about autism-related milestones. This is routine and not cause for alarm. Biting and hitting sometimes show up around now, usually out of frustration. Stay calm, say "no biting" firmly, and redirect. Check that your car seat is still installed correctly and the right size.
For you
Tantrums are hard on everyone. But when they pass, your toddler comes back to you for comfort. You're their safe place. That means everything.
Caution
18-month developmental screening
The AAP recommends autism screening at 18 months. This is a critical checkpoint for identifying developmental concerns early.
What to do
Attend the 18-month well-child visit. Complete any screening questionnaires your pediatrician provides. Discuss any concerns about social interaction, communication, or repetitive behaviors.
Caution
Car seat safety check
Ensure your child is still rear-facing in their car seat. The AAP recommends rear-facing until at least age 2 or until they exceed the car seat's weight/height limit.
What to do
Keep car seat rear-facing. Check that the harness fits snugly. Verify the seat is installed correctly. Never use a car seat that has been in an accident.
Good to know
Biting and hitting
Toddlers may bite, hit, or push when frustrated, angry, or overwhelmed. This is common but needs consistent, calm guidance.
What to do
Stay calm. Say 'No biting. Biting hurts.' Comfort the other child first. Help toddler use words for feelings. Never bite back as punishment.
