Ages 12 to 36 months

A toddler handbook for parents of children 12 to 36 months

A handbook for the parent holding the phone. Pick the season your child is in, open the one problem running the week, and walk into the visit with a clearer question.

Best for: parents, grandparents, and other caregivers of children 12 to 36 months who want one page on sleep, food, behavior, or the next visit.

Start here See the seasons

A toddler in a sage shirt walks barefoot across a sunlit living room toward wooden toys while an adult in a cream sweater sits on the rug and watches. Woven baskets and a low bookshelf sit behind them.

How it works

A short path for a long month.

  1. 01Name the season.

    12 to 18, 18 to 24, or 24 to 36 months. Start here if you want the path written out.

  2. 02Open one page.

    Sleep, food, or behavior when the week is a habit. The blog when one problem is running the house.

  3. 03Bring the question.

    Write what you see. The clinician examines your child. CDC's line still holds: you know your child best.

What you can check

Public guidance, and the week in front of you.

  • CDC milestones

    Language follows CDC Learn the Signs. Act Early. The lists describe what most children can do by an age.

  • AAP screening ages

    General developmental screening at 9, 18, and 30 months. Autism screening at 18 and 24 months, plus any time a parent or clinician is concerned.

  • A family of six

    Three adopted. Half boys, half girls. Lived all over, and parented on both thin and comfortable budgets. Read the story.

A parent writes in a small notepad on a wooden waiting-room chair while a toddler in cream knit clothes sits beside them near a window and plants.

This week

What to bring to the 18-month visit

The American Academy of Pediatrics asks clinicians to use standardized screens at this visit. The page walks through what to write down before you sit down.

Questions parents ask

Before you open a page.

Who is this for?

Parents, grandparents, and other caregivers of children from 12 to 36 months.

What do I get when I start?

A season page for your child's age, then one article for the problem running the week: sleep, food, behavior, a visit, or safety. The same Start here path is on every page.

Where do the milestone lists come from?

CDC Learn the Signs. Act Early. The lists describe what most children can do by an age. They are a conversation tool for the well visit. CDC explains monitoring and screening.

When does the well visit include a screen?

The American Academy of Pediatrics recommends general developmental screening at 9, 18, and 30 months, and autism screening at 18 and 24 months, plus any time a parent or clinician is concerned.

What are the quizzes?

Seven short choices and a label you can text to the group chat. The handbook and the well visit stay the standard. They live on the quiz hub.

Who writes it?

A family with six kids, three of them adopted, who have lived all over the country and parented with both thin and comfortable budgets. If a week has no new AAP or CDC reason to publish, we skip. That story is on About.

From our family

Six kids. Every kind of month.

  • Six kids
  • Three adopted
  • Half boys, half girls
  • Lived all over
  • Been poor and rich parents

ToddlerGuide is built by a family with six kids (three adopted, half boys and half girls) who have lived all over the country and been both poor parents and rich parents. We’ve done the 2 a.m. googling, the hand-me-downs, and the “is this normal?” spiral. This site is the ages-and-stages handbook we wish we’d had on our phones: warm when you need a friend, careful when safety matters, and never pretending every toddler is the same.
