Early morning. She is awake before either of you, and this is the first thing she hears all day. Short lines, said softly — that is the whole register.
Three in the morning and she is crying. Nothing here is a sentence you would build from a grammar table — it is sound, repetition and closeness, which is exactly what soothing is in any language.
The changing table, six or eight times a day. It is the most repeated conversation you will ever have with her, which makes it the best place in this deck to build a habit.
A feed, at whatever hour it happens. Notice how little of this is instruction and how much of it is simply keeping her company out loud.
Bath time, both of you in the bathroom. These two are from Buenos Aires, so you will hear the Argentine verb endings — the stress lands on the last syllable and the informal 'you' form changes shape.
Getting her dressed, one limb at a time. The cast is Chilean here — the fastest Spanish in the region, and the /s/ at the end of a word often disappears. Use the slow replay.
The ten minutes before you leave the house, which is a conversation between the two of you as much as with her. Mexican vocabulary here — the stroller and the pacifier have different names in almost every country.
On the floor with her, being ridiculous. This is the part of the register no course teaches, and it is where most of the hours actually go.
She has found something she should not have. Correction in this register is quiet and short — the volume does no work, and the diminutives do not disappear just because you are saying no.
The last thing she hears. The lines get shorter and slower as the routine goes on, which is the whole technique — say less, say it lower, say the same thing again.
