One thing that I keep telling DS5.5 is that we can't always have everything just the way we want it, and sometimes we have to make decisions or deal with certain situations as they are, no matter how difficult (or boring).
That's why I like to think of a child's readiness level. It is a zone of difficulty. If the child is way beyond what is being taught, then the situation has to change. If the child has some subject that are 'interesting but not a challenge' and even a few where there is a 'challenge that requires really learning how to learn' then it is time for the 'we can't always have everything the way we want it' speech.
If we don't actually know what the child's readiness level is, then we don't know what to do or say! And our little gifties sometimes take unpredictable leaps forward... which can explain lots of mysterious behavior.
In fact, if a parent was theoretically able to make everything 'perfect' for the child, in terms of readiness level, for years and years, when everyone else is getting 'off the rack' education, it sort of sends the message to the child that they are fragile and vulnerable. So we need to make the environment reasonable (not perfect)and then be cheerleaders for our children to be flexible. But we have to get the environment reasonable First. (IMHO)
