Unlock Sleep: Conquer 12-Month Separation Anxiety & Developmental Leaps Your 12-month old is changing fast, and those big developmental steps often show up as sleep disruptions and clingy evenings. This guide gives gentle, practical strategies you can use tonight to soothe separation anxiety, protect naps, and support healthy sleep through developmental leaps.
