How to change diapers at night without waking baby?

To minimize disruption during a midnight diaper change, keep the environment dim and maintain a 'no eye contact' policy. If your baby starts to smile or engage with you, avoid responding with active play; keep your interactions neutral and quiet. Some parents find that offering a dream-feed or a small amount of pumped milk during the change helps keep the baby calm and sleepy, allowing them to drift back to sleep immediately after.
