When to Start Sleep Training?

When should you begin sleep training your baby? Most experts agree that 4 to 6 months old is the ideal time to start.

Several factors contribute to this recommended age range:

Physical Development: By 4 months, babies can typically sleep for six to eight hours overnight without needing a feeding. This is a key indicator of readiness. (Source: Whattoexpect.com, Taking Cara Babies, Cleveland Clinic )
Developmental Readiness: Babies at this age are beginning to develop the ability to self-soothe and fall asleep independently. (Source: Sleep Foundation, BabyCenter)
Minimizing Sleep Associations: Before 4 months, comforting from parents easily becomes a sleep association. After 6 months, breaking these associations can be more challenging. (Source: Whattoexpect.com, Pampers)

Considerations:

Individual Variations: While 4-6 months is a guideline, some babies may be ready earlier (as early as 5 months), while others may benefit from waiting a bit longer. (Source: Taking Cara Babies, Nested Bean)
Weight and Health: Some sources suggest a minimum weight of 12 pounds and a pediatrician's approval before beginning sleep training. (Source: Pampers)
