I don’t know how ballet dancers actually stand on their toes, so this is probably the wrong term, but I don’t know else to describe it...
My DD is 2 and a quarter. She recently started walking on tiptoe but not like you normally walk on tiptoes: her toes are bent under, so she’s walking on her toe knuckles.
My other 2 DCs and I have all tried to do it, but can’t. Has anyone else had a child do it? I’ve never seen it before. I don’t imagine it’s anything to worry about but it is rather fascinating.
