Should I be doing anything about it? I'm not convinced that there is anything that would help or that I should be doing, but I question it every few months and wonder again.
If there were something to do, then sure, do it. But some LD's can't be helped, just have to be 'worked around.' I think the key thing in DD's case is to hold in your mind that 'in a way' she may be HG or PG, even though 'in other ways' she is the classic HG + LD = MG equation. If you at least hold that in your mind, then when the opportunity for her to leap ahead in some area that she isn't held back by the LD, you'll be more likely to give that little extra push at just the right moment.
Love and More Love,
