From Baby to Toddler: When Sleep Becomes a Boundary Issue

Toddler Sleep Training

Short Answer:

Toddler sleep training focuses less on sleep biology and more on behavior, boundaries, and emotional consistency, because toddlers have strong opinions, memory, and the ability to negotiate.


Why Toddler Sleep Is Different

After 12 months, sleep challenges are driven primarily by:

  • Strong sleep habits

  • Increased independence

  • Language and negotiation

  • Separation anxiety and fears

Unlike infants, toddlers understand routines — and test them.

When Toddlers Actually Need Sleep Training

Not all toddler sleep issues require formal training.

Sleep training may be helpful when:

  • Bedtime becomes prolonged or chaotic

  • Toddlers require a parent present to fall asleep

  • Night wakings involve calling or leaving the bed

  • Naps interfere with night sleep
