Free movement means 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, comfortable clothing, and an attentive presence. This principle stems from the work of Hungarian pediatrician Emmi Pikler, carried out in Budapest from the 1940s onward.
Where does free movement come from?
Emmi Pikler ran 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 stages, in the same order, without needing help to do so.
Her observations were published and taken up in France from the 1970s onward, particularly in nurseries and early childhood care settings. The term then spread among the general public.
An honest point needs to be made here. Pikler's work is based on rigorous longitudinal observation, not randomized controlled trials. To date, there is no solid 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 into 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 walkers reduce the movement available.
- Dress the child in comfortable clothing. Tight clothing or a diaper that is too thick restricts pelvic rotation.
The adult remains present but does not interfere with the movement. They talk to the child, keep them safe, and wait. This supportive approach is in line with 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 laying the baby down. In 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 tummy each day, spread throughout waking periods.
From 4 to 9 months
This is the period of rolling over, pivoting on the tummy, then crawling. The child moves independently from back to tummy, then makes the reverse journey. They begin to move around, often by moving backward at first.
Sitting up happens naturally, generally from a crawling position. A child who can sit up alone also knows how to sit back down alone if they lose their balance. That is the whole difference from a child positioned by an adult.
From 9 to 18 months
The child pulls themselves up, moves along furniture, then lets go. Independent walking most often begins between twelve and eighteen months. This is a wide and perfectly normal range.
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 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 but the duration. A baby who spends several hours a day in a semi-seated position loses valuable floor time.
The wheeled baby 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 using it.
From a motor-development perspective, a baby walker places the child in a standing position before they can achieve it alone and puts them into a toe-supported stance. It does not save time. Several studies have even observed a slight delay in walking development among regular users.
How should you arrange the floor to encourage free movement?
The setup matters more than the equipment. Three elements are enough.
A firm, flat 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. If it is too thin, the mat does not protect against the tiled floor. If it is too thick and soft, it becomes a mattress. The materials and safety of foam mats deserve close attention before purchase.
Our 15 mm XPE foam foldable and reversible play mat was designed for this purpose: firm enough for support, cushioned enough for those first tumbles, and foldable so the room can be cleared in the evening.
An open space
Allow at least two square meters of open space, with no furniture with sharp corners in the immediate vicinity. The child should 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 shown in our article on creating a Montessori-inspired play area.
Fewer, carefully 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 grasp and when.
The most common mistakes
Three pitfalls frequently arise for 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 rhythms vary greatly. A child who crawls at ten months is not behind.
The third is a cold floor. Eighteen-degree flooring discourages floor time, even with the best intentions. This topic comes up regularly among the common mistakes surrounding play mats.
When should you be concerned?
Free movement does not replace medical monitoring. 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 acquisition that had already been established.
A parent's concern is, in itself, a legitimate reason to seek medical advice. Healthcare professionals regularly reiterate this. Our article on identifying neurodevelopmental disorders before age 3 details the process in France.
Key points to remember
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 products at Treelys®: fewer items, chosen to last.
If you only remember one thing: place your baby on their back, on the floor, and let them do it themselves. The rest comes naturally. Our approach and commitments are detailed on the About Treelys® page.
