1 month olds need to sleep quite often; aim to give your baby the opportunity to sleep after about 30 - 90 minutes of wakefulness. Look for sleepy cues to help determine when your newborn will be ready to sleep.
When your baby starts looking away from you, getting a glazed-far away look in their eye, or rubbing/putting their forehead on you, there’s a good chance they’re ready for a little snooze. Ideally, you’ll give your baby a chance to sleep before they reach the overtired stage, which makes it harder for them to fall asleep.
