Modding question about the new life state

In the sim data age section it used to look like this:

<T type="Int64">1</T> Baby

<T type="Int64">2</T> Toddler

<T type="Int64">4</T> Child

<T type="Int64">8</T> Teen

<T type="Int64">16</T> Young Adult

<T type="Int64">32</T> Adult

<T type="Int64">64</T> Elder

Does anyone know if and how this has changed? I had wondered if maybe baby became 0 and infant 1?
