Ah, the million-dollar question for new parents: When do babies *really* sleep through the night? While the dream is a solid 8 hours, the reality is often more nuanced. Generally, most babies *can* physiologically sleep through the night (around 6-8 hours) by 4-6 months old. However, 'can' doesn't mean 'will'!
Several factors influence this milestone. Weight gain is crucial; babies need to be able to go longer stretches without needing to feed. Developmental leaps, teething, and illnesses can also disrupt sleep.
Establishing a consistent bedtime routine can work wonders. Think bath, story, lullaby – anything that signals 'sleep time' is approaching. Avoid creating sleep crutches like rocking or feeding to sleep, as these can become dependencies. Remember, every baby is different! Be patient, persistent, and celebrate small victories. And don't be afraid to seek advice from your pediatrician or a certified sleep consultant if you're struggling.
