DD1, KS3, bright academically, aces tests and exams, tends to procrastinate (gets that from me!), good at sport, kind of person life comes easy to...so far
DS, KS2, best in class at maths by some distance, average-ish in other subjects, works hard, good problem solver, good at sport, competitive
DD2, KS2, amazing memory, very creative with words, avid reader, well above average across the board academically, procrastinates like mad, extremely focused on her own interests, seems to have difficulty with planning and execution.
I'd say they're all bright in different ways, but they all have things they'll need to work on/overcome. DH and I were both very strong academically (him more so than me), so I know it's not the be all and end all.
