The 6 month sleep regression is a temporary but challenging phase caused by major developmental milestones such as increased mobility, separation anxiety, and nap transitions. Babies at this stage may struggle with night wakings, shorter naps, and difficulty settling to sleep. To navigate this regression, parents can establish a consistent sleep routine, encourage independent sleep skills, ensure an appropriate nap schedule, and provide ample time for practicing new skills during the day. By staying patient and consistent, parents can help their babies adjust and return to better sleep patterns.
