Free movement consists of allowing the child to discover each position on their own, without ever placing them in it. Do not sit them up before they can sit up on their own, and do not stand them up before they can stand. The adult's role is limited to providing a safe floor, flexible clothing, and attentive presence. This principle comes from the work of Hungarian pediatrician Emmi Pikler, carried out in Budapest from the 1940s onward.
Where does free movement come from?
Emmi Pikler directed the nursery on Lóczy Street in Budapest. She observed hundreds of children there over several decades. Her conclusion could be summed up in one sentence: when free to move, children go through the same motor-development stages, in the same order, without needing help.
Her observations were published and taken up in France from the 1970s onward, particularly in nurseries and early childhood settings. The term subsequently spread among the general public.
A point of honesty is needed here. Pikler's work is based on rigorous longitudinal observation, not randomized controlled trials. To date, there is no strong experimental evidence showing that free movement produces better long-term motor outcomes than a more interventionist approach. What is well established, however, is the value of time spent on the floor and the risk associated with prolonged immobilization.
What are the practical principles of free movement?
The principle can be summed up in four simple rules that can be applied from the first few weeks.
- Never place the child in a position they cannot reach on their own. Do not use a cushion to prop them up in a sitting position or hold them under the arms to make them walk.
- Place the child on their back. This is the freest starting position: they can turn their head, move their arms and legs, and begin to roll over.
- Limit restrictive equipment. Bouncers, infant car seats, rocking seats, and baby walkers reduce freedom of movement.
- Dress them in comfortable, flexible clothing. Tight clothing or a diaper that is too thick restricts movement of the pelvis.
The adult remains present but does not intervene in the movement. They comment, provide reassurance, and wait. This supportive approach echoes the one described in our article on free play and creativity.
At what age should free movement begin?
From birth, in practice. This is not an activity to schedule, but a way of positioning the baby. During the first few weeks, a few minutes on the floor after each diaper change are enough.
From 0 to 4 months
Baby lies on their back, with arms and legs free. They turn their head toward sounds, track an object with their eyes, and wave their limbs. Tummy time is gradually added in short, supervised sessions.
The World Health Organization recommends that infants who are not yet mobile spend at least thirty cumulative minutes on their stomach each day, spread throughout their waking periods.
From 4 to 9 months
This is the period of rolling over, pivoting on the stomach, and then crawling. The child moves independently from back to stomach, then makes the reverse journey. They begin to move around, often backward at first.
Sitting comes naturally, generally from the crawling position. A child who sits up independently also knows how to sit back down alone if they lose their balance. That is the key difference from a child propped up by an adult.
From 9 to 18 months
The child pulls up to stand, moves along furniture, and then lets go. Independent walking most often begins between twelve and eighteen months. This range is broad and perfectly normal.
The precise milestones in this progression are detailed in our article on fine and gross motor skills from 0 to 3 years.
Should you ban the baby bouncer and the baby walker?
No to the baby bouncer, yes to the baby walker. The distinction matters.
A baby bouncer is useful for a few minutes a day, while taking a shower or eating a meal. The problem is not the item itself, but the amount of time spent in it. A baby who spends several hours each day in a semi-seated position loses valuable floor time.
The baby walker, or wheeled walker, presents a different problem. It is associated with a documented risk of accidents, particularly falls down stairs. Canada banned its sale as early as 2004. In Europe, it remains permitted under the EN 1273 standard, but many healthcare professionals advise against its use.
From a motor-development perspective, a baby walker places the child in a standing position before they can reach it independently and keeps them supported on tiptoe. It does not speed things up. Several studies have even observed a slight delay in learning to walk among regular users.
How should you arrange the floor to support free movement?
The setup matters more than the equipment. Three elements are enough.
A firm, level surface
This is the key point. A soft surface absorbs the force from the arms and knees, making movement more difficult. A thick but dense mat provides the necessary support while cushioning falls.
A thickness of around 15 mm in cross-linked foam strikes a good balance. Too thin, and the mat does not protect against the tiled floor. Too thick and soft, and it becomes a mattress. The choice of materials and safety of foam mats deserves careful consideration before purchase.
Our foldable, reversible 15 mm XPE foam activity mat was designed for this purpose: firm enough for support, cushioned enough for those first falls, and foldable so the room can be cleared in the evening.
An uncluttered space
Allow at least two square meters of open space, with no furniture with sharp corners in the immediate area. The child must be able to roll without bumping into anything. A space that is too narrow produces exactly the effect that free movement seeks to avoid.
The room's layout matters as much as its size, as our article on setting up a Montessori-inspired play space shows.
Fewer, well-chosen items
Three or four items are enough: a scarf, a lightweight ball, a wooden ring, and a basket. They are placed on the floor within reach, never suspended above the child's face. The child chooses what to grab and when.
The most common mistakes
Three pitfalls commonly arise among parents discovering this approach.
The first is dogmatism. Free movement does not mean you cannot carry your child, cuddle them, or sit them on your lap. It concerns independent positions, not parents' arms.
The second is comparison. Age ranges are broad and developmental timelines vary greatly. A child who crawls at ten months is not behind.
The third is a cold floor. Eighteen-degree tile flooring discourages floor time, even with the best intentions. This topic regularly comes up among the common mistakes surrounding activity mats.
When should you be concerned?
Free movement does not replace medical follow-up. Certain signs warrant discussing them with a doctor or pediatrician without waiting for the next appointment.
- No head control after four months.
- Marked asymmetry: the child always uses the same side.
- No rolling over by eight months.
- No independent movement by twelve months.
- Loss of an already acquired skill.
A parent's concern is, in itself, a legitimate reason to seek advice. Healthcare professionals regularly reiterate this. Our article on identifying neurodevelopmental disorders before age 3 details the pathway provided in France.
Key takeaways
Free movement requires neither expensive equipment nor a complicated method. It requires floor space, time, and patience. It is a simple approach that reflects how we design Treelys® products: few items, chosen to last.
If you remember only one thing: place your baby on their back, on the floor, and let them do it themselves. Everything else follows naturally. Our approach and commitments are detailed on the About Treelys® page.
