'Master of None' makes a really good point.

I mentioned using relative strengths and weaknesses to help my sons adjust, but she points out that a child does not need attention drawn to weaknesses when their strengths are being acknowledged. For us, we moved straight from a scenario where my sons were obviously weak (sports) to one where they were seeking a reason why their same aged friend couldn't read. However, if I spoke about their difficulties each time their strengths came up it would cause difficulties for them, in terms of self-esteem. One of my sons is particularly sensitive in this way.
