Stop sleep regressions

Rolling, sitting up, teething: New milestones can mean sleep regressions. Add the gently weighted Zen Sack to your sleep routine to help create positive associations with bedtime.

Help baby sleep through the night

Nighttime wakeups? The gently weighted Zen Sack is so comforting, it helps babies self-soothe—so they fall back to sleep on their own.
