Are you a new parent wondering when to start sleep training your little one? The answer may vary depending on your baby's age and development, but most experts recommend starting between 4 and 6 months. At this age, babies have established a regular sleep pattern and are able to self-soothe. By implementing a consistent bedtime routine and gradually teaching your baby to fall asleep on their own, you can help them develop healthy sleep habits that will benefit them for years to come. Don't wait too long to start sleep training, as the longer you wait, the harder it may be for your baby to adjust to a new routine.
