When I am helping my young child say Birkat Hamazon or other prayers, I sometimes correct her pronunciation of a word or prompt her when she forgets what the next word is. In these situations, she frequently continues from the next word after the one I said, without repeating or saying the word I supplied, as if my saying it was part of her recitation.
As a matter of effective training for correct observance in the future (which I understand the purpose of her prayer and of my helping to be):
Is it problematic that she skips the word I say in this manner?
If so, do you know of any good, preferably non-disruptive, ways to prevent such skipping while providing the correction or prompt required?
