There is no single 'correct' method
Sleep training approaches range from very gentle to more structured, and what works well for one baby and family may not suit another. Consistency in whichever approach you choose tends to matter more than which specific method you pick.
Progress is rarely a straight line
Expect setbacks around growth spurts, illness, or travel -- a few rough nights do not mean the routine has failed. Returning to the familiar routine afterward usually gets things back on track.
Frequently Asked Questions
At what age can I start sleep training?
Opinions vary, but many pediatric sources suggest gentle routines can start from birth, while more structured self-soothing methods are often introduced somewhat later, around four to six months. Ask your pediatrician what is appropriate for your baby.
Is it okay to let my baby cry a little while learning to self-soothe?
Views on this differ, and there are several methods with different levels of parental involvement. Choose an approach you're comfortable with, and talk to your pediatrician if you are unsure.
