What customers say: This sleepsuit is praised for helping babies transition from swaddling, calming the startle reflex, and improving sleep duration; however, some find the micro-fleece material too warm or the sizing a bit snug.
★★★★☆

Effective, but sizing can be tricky

Gabriela E. · 2025-10-30 · Verified purchase

This sleepsuit does an excellent job of calming the baby's startle reflex and helping with sleep. However, we found the Small size (12-18 lbs) a bit tight when our baby hit about 17 lbs. It made bedtime a slight struggle getting his arms in comfortably. Otherwise, it works well.

★★★★★

Better sleep for everyone

Monica R. · 2025-10-01 · Verified purchase

We were desperate for a solution to our baby's short sleep cycles, and this was it. The sleepsuit gives him that cozy, secure feeling he loves. He's sleeping for much longer stretches, which means we are too. An absolute must-have for parents.

★★★★★

So soft and cozy

Monica M. · 2026-03-09 · Verified purchase

The micro-fleece material is incredibly soft, and our baby loves the cozy feel. It truly helped bridge the gap between swaddling and a regular sleep sack. We saw an immediate improvement in his sleep duration. Would recommend for fussier sleepers.

★★☆☆☆

Too warm for our climate

Morgan C. · 2026-08-07 · Verified purchase

The micro-fleece material felt very thick and warm. Even though it's rated at 1.0 TOG, my baby seemed to overheat in it, especially in our warmer house. We had to stop using it because he would wake up sweaty.

★★★★★

A true sleep solution

Stephanie S. · 2025-09-02 · Verified purchase

Our baby moved from swaddling easily with this. The micro-fleece is soft, and the design seems to really help prevent the startle reflex. We noticed an improvement in his sleep within a few nights. The double zippers are very practical.
