The First Year With a Pikler Triangle: When Your Child Doesn't Climb
Share
I bought a Pikler triangle well before my son turned one. I had pictured what would happen: he would climb, I would take the photo, and the frame would earn its place on day one.
That is not what happened. At one year old he had no interest in it as something to climb. He lay underneath it. Crawled through. Came back. For him the frame was a place, not a challenge — a shelter to go under.
It took me a while to see that this was not a failure. It was exactly what Emmi Pikler's idea is about.
A climbing frame is not a task to complete
The core of Pikler's thinking is that a child develops movement on their own timetable, without an adult lifting them into positions they cannot reach by themselves. The frame is an offer, not a programme. If a child chooses to lie down, they have chosen to lie down.
This is also a safety point. A child who climbs up on their own can usually get back down. A child who was lifted up cannot.
What the first year actually looks like
Children differ and there is no schedule, but broadly this is the sequence parents describe:
- Around 6–10 months: the frame is support. The child pulls up against the rungs and stands for a moment. There is no climbing.
- Around 10–15 months: the frame is a place. Going underneath, crawling through, leaning on it. For us this phase lasted a long time.
- Around 15 months–2 years: the first steps up. Usually one rung at a time, over and over.
- From 2 years: climbing over the top, the ramp, sliding, and rules invented on the spot.
If your child stays in one phase for months, nothing is wrong. The money was not wasted — the frame is in use, just not in the way you pictured.
A den is a correct way to use it
What I first read as the “wrong” use turned out to be the best one. A climbing frame works as a den because it is a child-sized space the child can choose for themselves. Throw a blanket over the top and underneath there is somewhere that belongs to them.
One thing worth knowing: den play and climbing do not belong in the same moment. With a blanket over the frame, climbing is not safe — the child cannot see the rungs or judge the grip. Take the blanket off when the climbing starts.
For a den, an arch beats a triangle
If your child mainly uses the frame as a place, an arch is the more practical shape. A triangle is a triangle: the space underneath narrows as it rises. Under an arch there is a low, open space a child can lie down full length in, and it is open at both ends, so they can get in and out from either side.
An arch also does three things a triangle does not: it rocks, it flips over into a balance board, and it is low, which makes it less daunting for a child who hesitates at height.
Ours is the Montessori climbing arch — Baltic birch plywood, EN 71 certified, 50 kg load.
Four things that helped here
- Location decides everything. A frame in the corner of the child's room goes unused. I moved ours into the room we were already in, and it started being used.
- Don't demonstrate too much. Showing it once is enough. Repeated encouragement turns the frame into the adult's idea.
- Soft floor, clear surroundings. Coming down is part of climbing. Leave clearly more space around it than its own footprint.
- A break works. If it has gone untouched for a month, put it out of sight for a couple of weeks. Brought back, it is new again.
Which model I would choose now
If I were starting over, I would start with an arch or a low two-segment triangle, and move to a modifiable model only once climbing had genuinely begun. The most expensive and most versatile one is not the best first frame — it is the best second one.
I put four models side by side in one table: price, recommended age, climbing height, load capacity, certification and the space each one takes. Compare Pikler triangles →
