Helped with sleep regression

This sleepsuit definitely helps our baby sleep through regressions.

★★★★☆

Good, but sizing ran small

Sabrina L. · 2025-09-28 · Verified purchase

The sleepsuit works, but the Small size was snug for our 16 lb baby.

★★★★☆

Effective but bulky

Lindsey K. · 2026-05-21 · Verified purchase

This suit really does help keep my baby settled and reduce the startle reflex. It's quite bulky, which makes him look a bit like a marshmallow, but it's effective for sleep. The double zippers are super handy.

Wonderful for sleep regressions

Megan C. · 2025-10-13 · Verified purchase

We were in the thick of a sleep regression, and nothing was working. This sleepsuit made an instant difference. The cozy, contained feeling really calms our baby, helping her settle down and stay asleep. We are all so much happier.

Happy baby, happy parents

This sleepsuit is incredible for improving baby sleep. Our little one stopped startling herself awake and now sleeps for solid stretches. The cotton material is soft and seems comfortable for her, and it washes up nicely.
