What this class is

Most parents notice a real shift around the third birthday that does not match the cultural narrative of the terrible twos. The three-year-old is more verbal, more capable, and meaningfully harder in different ways than the two-year-old was. This class names what is happening.

Gaux built this because the toddler discourse skips year three. Developmentally, year three is a major reorganization — theory of mind, emotional regulation, social capacity, and self-concept all move at once — and the household tends to feel it before anyone has a word for it.

It is taught by a credentialed Gaux professional who works with three-year-olds regularly. The class is built to help you read the year three signal as growth rather than regression.

What you get

  • A short class on one toddler-and-beyond moment, from someone who works with families daily.
  • Scripts and frameworks you can carry into the next hard hour.
  • Watch on your own time; the rest of the library opens with membership.

What you’ll learn

  • What major developmental shifts happen between two-and-a-half and three-and-a-half, and what that looks like at home.
  • Why year three often feels harder than year two, even when the child has more language and more skill.
  • How emotional regulation typically develops at this age and where the gaps tend to show.
  • How to support a child whose social world is suddenly more complicated and whose feelings are bigger than the words.
  • Which routines from year two still work, which need to change, and how to make the change without a fight.
  • How sleep, eating, and toileting often shift in this window and what is typical versus worth flagging.
  • What to expect of year four if year three has been intense.

Who it’s for

Parents and caregivers whose child is approaching, in, or just past the third year. Also useful for educators and other adults regularly in a three-year-old's daily life.

Common questions

Is year three really harder than year two?

For many families, yes. The class explains the developmental reason rather than treating it as bad behavior.

When do tantrums get easier?

Tantrums usually shift in flavor before they decrease in frequency, and the class describes the curve.

Is it normal for sleep to regress at three?

Common, often tied to developmental gains rather than sleep itself. The class covers what to do.

What is the difference between year three and year four behavior?

The class names the contrast directly, and the dedicated four-year-old class picks up where this one ends.
