The 4 month sleep regression can show up as sudden night waking, shorter naps, harder bedtimes, or a baby who seems harder to soothe than before. Around this age, sleep patterns begin to mature, which can make sleep feel lighter and more disrupted for a while. Many parents search for 4 month sleep regression signs because the change can feel abrupt, even when it is a common developmental shift.
A 4 month sleep regression waking every hour pattern is one of the most common concerns. Babies may move between sleep cycles more noticeably and need more help getting back to sleep.

A 4 month old sleep regression may also show up as fussier evenings, longer settling, or a baby who suddenly needs more soothing at bedtime.
