And if, as you contend, five and six-year-olds are quite capable of keeping up with all the ins and outs of the plot as it appeared on screen (and I know I wouldn't have been at that age), then we have the even worse image of an apparent seven/eight-year-old shooting an adult dead earlier in the story - and worse than that, that adult then appears alive and well five minutes later, showing that there's no consequence to such an action.
Small children generally watch television in terms of the images presented rather than the subtleties of meticulous plotting (read the report on Image of the Fendahl, and DWM's own feature on Terror of the Zygons), and the image presented at the very end of the episode was of a pregnant woman shooting a child. That really is what we saw (or appeared to see) right at the very end there.
