I am after some advice as someone who had no siblings and am now a single parent. Ds1 has always done extremely well at school and just got all 9s in his mocks, which is fantastic, of course. Ds2 is two years younger and also does well - is in top sets and tends to get mainly 7s in assessments, with a smattering of 6s and 8s and the odd 9. (The school gives GCSE 'grades' as WAGs from Y7, which I don't really understand but it obviously gives a rough indication of how they're doing).
I am worried about how to speak about ds1's achievements in front of ds2 without causing feelings of inadequacy/jealousy, while at the same time giving ds1 the praise and attention he deserves. Obviously, we don't know what will happen in the summer, but most subjects used the 2019 grade boundaries and he was well into 9s. He is very hardworking as well as able so the likelihood is his GCSE results will be extremely impressive (not that I'm assuming all 9s or assuming anything really).
I know ds2 compares himself, sometimes unfavourably and I don't know how to deal with it. Certainly I don't make negative comments about him or compare him myself but he seems to be doing that himself. He's able, but nowhere near as driven as ds1, who also has interests/hobbies that complement school work, while ds2 would sit on tiktok all day if I let him.
Ultimately, I think ds2's grades are great and he is conscientious enough. If he stays as he is I feel like he'll do well while Ds1 just has this immense drive from within that I'm not sure ds2 should or can even try to emulate, but I don't want to come across as negative about his potential or ability. I also don't want anything like this to spoil their relationship, which is pretty good, notwithstanding the usual sibling squabbles. Any advice on how to deal with this would be great.
