Pikler Triangle: To Have or Not To Have

My daughter is a highly curious, very active 11 month old toddler, so this may just be the beginning of watching her climb while quietly worrying.

Our neighbors offered us their 2ish ft Pikler Triangle, with the slide. I think my daughter would use it. She loves when I open the gate and let her climb the stairs, and I rarely have to stop her from falling. We go to the park daily and she climbs around on the equipment.

Im comfortable with the idea of her falling from a short height. We’d put a mat underneath. But I keep picturing her getting a foot or leg caught in the rungs as she falls, and breaking her ankle or tibula/fibula.

Are these serious injuries common? Do those of you who use them find that they’re worth it?
