Protects limbs from slipping out

The absorbent front and back are wide, and it's thinner between the legs. This helps to preserve a neutral position of their limbs.

The ideal position is the bottom and the soles of the feet to be in the same line!

Hugs limbs correctly

The crotch area is snug so that it's easy to understand where the baby's bottom is, hugging their knees correctly.


Support for "positioning"

It's widely known that the right positioning can support healthy body and brain growth, and also influence their attachment formation to their mother. These are constructed to preserve the correct positioning.

Tape diapers

When changing a baby's diaper, you need to lift up their waist high.

Moony Flat

Since this diaper has a compact length, you don't need to stick in a lot of length. That means you don't need to lift up their waist when changing.

Current state*

Diapers that are stiff or have wide absorption areas can let limbs slip out.

Moony Flat

The area between the legs is slim and the diaper is soft, so it preserves the position of your baby's limbs.

The Support for Small Lives Project

We work to provide a better environment and society for families raising a child born in the NICU.

Every birth is a miracle

Currently, about 1 million babies are born in Japan annually.

Each and every baby's body, personality, and appearance is different.

To be blessed with this miracle of life is a truly wonderful thing.

And the process of childbirth is something that families, nurses, midwives, doctors, and so many people create.

You could say it's a miracle that everyone works together to create.

Thank you to this small but growing life.

ーVoices of Gratitude from Moms and Dadsー

I've realized the magnitude of life.
I watched this with my daughter.
Thank you so much.

This made me cry after a hard morning.
The baby worked so hard, too.
This really moved me.

My twins went to a NICU when they were born. The NICU was always a warm and calming place.
My babies tried their best, so I did as well. It made me experience the will to live as they grew day by day.
Moms, don't push yourselves too hard; trust your baby and overcome it together. Your baby is certainly proud of you.

The NICU/GCU took care of my child for about one month.
I felt so guilty for them being born so small, but with the help of the NICU doctors and nurses, we were able to be discharged safely.
You probably panic when you hear "NICU" but it's a place where they will give your baby and your family nothing but comfort and support with their thorough care.
Ask them anything if you feel the least bit worried. They'll give you reassuring words.
