I've recently begun visualising a particular scene from what will be the end of the novel I'm currently writing. I hit a wall when I realised I don't really know too much about when children begin to walk and talk etc. I hope you can enlighten me a bit on this topic. In this scene there needs to be a specific verbal exchange between a young girl and her aunt's boyfriend (she lives with them as both her parents are dead) one day when the two are on their way home after attending a funeral. The girl notices the man's eyes change colour, something she's never seen before and didn't think could happen, and asks him why his eyes changed colour. The man doesn't know and asks her something along the lines of "Did they really? When did this happen?" and the girl replies that she thinks it must have happened only a few minutes earlier. The man the whips out a mirror, confirms that his eyes have changed colour and then bring the girl over to a couple of other people in the vicinity to see if their eyes changed colour too. How old does the girl have to be for this to be realistic (I wonder mostly because this is important in calculating when it's realistic that her parents died)? She needs to walk by herself, talk and understand questions and answers, be fit to attend a funeral and not freak out too much when she sees a person's eye colour change (or maybe that last one is freakier the older you are ... ?). I might as well mention that they both have magical powers (not that the girl can use them for anything useful yet), but that has little to no bearing on how quickly she grows up. Feel free to ask me additional questions if you have any. And you're also welcome to only comment on specific elements you know something about or think are unrealistic instead of considering all the factors. Thanks in advance.
