just an ankle sleeve with a LED button.
In simple steps, Necoron removes stress from
everyday parenting.

Science-Backed Support
for Baby Sleep

While at RIKEN, Dr. Kumi Kuroda and her research team discovered an arms-to-crib transfer
method that helps babies stay asleep during the process.
First, when your baby is fussy from sleepiness,
hold and walk with them for about 5 minutes, keeping a steady pace without stopping.
Once they fall asleep, hold them for another 5 to 8 minutes before laying them down.
This helps them stay asleep when placed in bed.

5-min Walk & Hold
5-8-min Sit & Hold
Lay Baby Down

The research team developed a heart rate‒based method—not just visual cues—
that gauges a babyʼs condition and signals the best next action.
Building on this foundation, Tomy developed a proprietary mechanism.
