Question: how long does it take for a baby to learn to self soothe?
Answer: Master the timing. Many parents start noticing their infant demonstrating self-soothing behaviors by 3 to 4 months. By 6 months, most infants are capable of going 8+ hours without needing a feed in the night, so it's an ideal time to encourage them to self-soothe themselves to sleep — and back to sleep if they wake up.
