Toddler Milestones by Month: 12 to 36 Months

Six pages follow CDC’s checklists (12, 15, 18, 24, 30 and 36 months), paraphrased by area with the skills and activities behind each item. The 19 months in between show which checklist applies (CDC: use the earlier one) and what is emerging next. Milestones are for monitoring, not screening: talk to your pediatrician about any worry.

All 25 pages in 6 groups: 12-month checklist (12-14 months) (3), 15-month checklist (15-17 months) (3), 18-month checklist (18-23 months) (6), 24-month checklist (24-29 months) (6), 30-month checklist (30-35 months) (6), 36-month checklist (1).
