Idr, it was one of her more personal conversations with another character, but I cannot narrow it down... I'll have to re-watch the series or trawl through transcripts to find it, but I'm busy tomorrow, so it'll be Saturday at earliest.

I have never heard of any child above 3 being a toddler, and as aura exists in remnant I assume some stages of basic human development occur at a slightly increased rate(which is the only way I can explain Yang getting as far from home as she did).

I think we can go with the idea that Yang was being at least a little dramatic when she described Ruby being a toddler.
