When DD was about 10 months old, she was able to walk around the edges of things by holding or leaning onto them. It was spring & we'd moved some furniture round, & a radiator was exposed that previously hadn't been. One day she was exploring the living room, I was sitting in the armchair opposite & she let out an ungodly screech, I looked up & she was leaning on the radiator. I swear I've never moved so fast in my life, I must have thrown myself across the room, (it was only a small house) & I landed on my bum the laminate floor with a skid, caught DD with my hands in front of me between my knees & hit the wall under the radiator with my feet. Thankfully, she wasn't burned but I washed her hands & face with cool water anyway. Afterwards, I made fleece blankets covers for all the radiators.
A neighbour's dog ran round into our unenclosed yard once when it heard toddler DD crying in her buggy. It was growling & barking at her, & only skidded to a halt when I stepped in front of her & screamed at it. It still wouldn't go away though, still barking & growling & coming towards DD, & DD was properly screaming (probably not helped by mummy shouting). I couldn't get her out as I'd have had to turn my back on it. The neighbour saw what was going on & called it off several seconds later, they obviously heard me shouting at their dog to leave my baby alone. I'd already locked the door & was stuck. We never saw their dog off its lead again, thankfully. And DD doesn't remember. I wasn't actually scared at the time. Only after, strangely.
And she fell all the way down the stairs once. Again, as a toddler. Complete somersault at the bottom, right through the safety gate which had a bar she could have brained herself on. Landed on the laminate floor in a heap & I was convinced she'd have broken something. Nope, a couple of bruises. Certain people weren't allowed to walk her up & downstairs after that though...
