For supervised exercise on the floor only. Not a sleep product.

A daily practice.

The Core comes with eight guided exercises. Each one uses the pillows and mat to hold a position you could not hold with your hands alone. New exercises are added as the program develops.

1

Elevated tummy time

The pillow lifts the chest to working height, so your baby can push up for longer with less strain, from the first weeks.

2

Guided massage

The pillow holds your baby steady and supported, so both your hands stay free to work along the back and legs.

3

Leg stimulation

The mat gives a firm, non-slip base to work against, so you can wake up the muscles your baby uses to kick, push and bear weight.

4

Upper back and pectoral stretches

Paired pillows hold the open-chest angle and leave both your hands free to release tension across the chest and upper spine.

5

Lumbar stretch

The pillow supports the lower back at a fixed angle, so you can gently mobilize the area with the position consistent every time.

6

Early anterior chain stimulation

The mat and pillow set your baby against a stable base, so you can activate the front-body muscles they recruit to lift the head, reach and roll.

7

Early rolling

The angle of the pillow starts the turn, so you can guide the rotation your baby needs to roll on their own.

8

Early crawling

The non-slip mat stays put under a baby who is pushing and pulling, so you can build the weight-bearing and reach that leads to crawling.

Every exercise comes with a video showing the setup, the movement, and what to look for, so you can do it with confidence at home.

Supervised use only. The Core is not for sleep.

Two halves of one system.

The Core is two things built for each other. A program of exercises, and the kit that holds each one at the right angle.

The exercises are the work. A guided practice for your baby's first months, the same positions, stretches and early movement Nicolas runs in clinic. The kit is what makes that work possible at home. Every exercise has an angle, and the pillows and mat hold it, so both your hands stay free to guide your baby.

Look at any exercise in the program and you see the same thing. Your baby on the pillows, the mat underneath, the work happening on top. The practice and the kit are one purchase because they are one system.

Elevated tummy time

The program that comes with your Core.

Every Core opens a complete video library, filmed by Nicolas. Each exercise from start to finish: how to set up the pillows, how to do the movement, and what to watch for in your baby as you go. The positions in the gallery, demonstrated step by step, so you can run them at home with the same confidence as in clinic.

The library sits in your free Fulkrum account, opened as soon as you order. That is where the videos are, alongside care guides, support from our team, and the other parents working through the same exercises with their babies. The program has a home, and your Core comes with the key.

The Core · The setup

Two pillows. One mat. Every exercise, set up right.

The pillows hold each position at the right angle. The mat gives you the firm, non-slip surface to work on. Together they are the setup behind every exercise in the program, sized for your baby from birth to nine months.

The Core kit: the pillow pair and mat set up on the floor

Where the real work happens.

Everything that matters in these months happens on the floor. Tummy time. Stretching. Massage. Early rolling and crawling. The slow build of strength through the whole body, and the daily practice that gets you there.

Getting that work right depends on the angle. The right support under the chest changes what tummy time does. Paired positioning opens stretches you cannot hold with your hands alone. Rolling and crawling stimulation depend on the body being held in exactly the right place while you guide the movement.

The Core is the kit built to hold those angles, so you can focus on doing the exercise with your baby.

What's in the box.

Baby in supported tummy time position on The Core

The pillows.

A matched pair, used from the first week through to nine months. Cotton and polyester cover over a memory foam core, firm enough to hold the angle under your baby's weight. Cover unzips and goes in the machine. Non-slip underside.

The mat

The mat.

Cotton and polyester cover over a silicone foam core. Firm, sized to seat both pillows, and it stays put under a baby who is pushing. Machine washable.

The laundry bag

The laundry bag.

100% cotton. Pack the kit to take it with you, or hold the covers in it on wash day.

A practice that grows with your baby.

The exercises change as your baby develops.

1

Weeks 1 to 6. Early positioning.

Short sessions of elevated tummy time on a single pillow. Both pillows together for the early stretches and newborn massage. A few minutes at a time, several times a day, building strength from the start.

2

Weeks 6 to 12. Strength.

Tummy time gets longer and less assisted as your baby's own strength comes in. Both pillows stay in play for specific stretches and release work. Massage adapts to your baby's growing tone.

3

Months 3 to 6. Movement.

Your baby is pushing up, propping, starting to roll. The exercises shift to early rolling, leg stimulation, and crawling preparation. Both pillows support the transitions, and the mat gives room to move.

Every baby develops at their own pace. The Core is sized from birth to nine months, so the kit stays with you as long as your baby needs it. Every exercise is demonstrated in the video library that comes with your Core.

For supervised exercise on the floor only. The Core is not a sleep product.

Used in clinic. Built for home.

The Core was prototyped, tested and refined inside the clinic before it was ever offered to families.

“The head control improvement was visible after just three weeks. The tummy time sessions are longer and more engaged.”

Elena Parent of a 3-month-old, Kuala Lumpur clinic

Because most of the techniques Nicolas teaches require two. Paired support during positioning, mirrored angles for stretching, a second point of contact during massage. A single pillow gets you partway. Two give you the full range of what the method is designed to do.
The Core is sized for your baby from birth to nine months. Daily use is most concentrated in the early months, when most of Nicolas's foundational work happens. Some babies finish using it earlier, others continue longer. Both are normal.
Daily use is most concentrated in the first months, when tummy time, positioning work, stretching and massage are foundational. Many families continue using the kit into months seven, eight and nine for stretching and movement support as the baby develops. Every baby develops at their own pace, and The Core is sized to stay useful across that range.
No. The Core is for supervised tummy time, positioning, stretching and massage. It is not a sleep product, and babies should not be left unattended on or around the kit. The labels on every component carry the same guidance.
Every Core comes with a complete video library. Nicolas walks you through every position, every stretch, and every massage sequence the system was designed for. Your account is created at checkout and the library opens straight away, so you can watch before your Core arrives. A printed user manual comes in the box.
Your access does not expire. The library stays in your Fulkrum account for as long as you have it, and new exercises are added as the program grows.

It is not required.
