Three Cliffs is coastal limestone, pretty solid, but on any crag like that there’s still loose stuff that can fall off the ledges and the top of the ridge. Unlikely, but possible, particularly as that part of the cliff has people scrambling above the routes a lot.
Top-roping is pretty much the most stable and safest form of climbing, but wearing a two-year-old on your back doesn’t exactly improve your centre of gravity and balance, and if she slips sideways or misjudges when she’s lowering near the base and goes onto her back, then kid gets a clunk.
At that age, my two were getting their arms out of their baby backpack straps whenever they felt like it – not the sort of thing you’d want if you’re 50ft up at the time.
Obviously, the most damning thing is that she considers it a climb requiring a helmet, but doesn’t consider it worthwhile providing one for nipper.
I think she’s equated the word ‘toprope’ with ‘safe’. Can’t see that the two-year-old will get much out of it either.
