Start with checking basic needs: feeding, diaper, or discomfort. If those aren’t the issue, use gentle soothing to help the baby resettle without full awakening.
Soothing approaches:
Try placing the baby down drowsy but awake to build self-settling skills. Avoid picking the baby up immediately for every whimper if they’re safe and not distressed — some babies resettle on their own. For persistent night waking or if you’re unsure whether to feed, check output and weight gain; consult your pediatrician for tailored advice.
