Can You Still Sleep Train at One Year? How to Reset Established Habits

Sleep Training at 10–12 Months

Short Answer:

Sleep training between 10 and 12 months is absolutely possible, but it requires clear boundaries, consistency, and realistic expectations because sleep habits are now well established.

What Makes This Age Different

By 10–12 months, babies:

  • Strongly associate sleep with routines and cues

  • Can stand, cruise, and call out

  • Understand cause and effect

  • Test boundaries more deliberately

Sleep training at this stage is less about biology and more about behavioral learning.

This is not true.

Sleep can still be reshaped — but it usually requires:

  • Firmer consistency

  • Fewer changes once training begins

  • Emotional steadiness from caregivers

  • On-demand interventions
