Ok, haven't posted in AIBU for a while so I'll take my chance.
I'm just pondering this morning really. I think Social Media, and perhaps especially Mumsnet has given me a warped idea that most dcs will be exceptionally talented at something.
Everyday I see posts on SM about outstanding musically achievement, sporting prowess, very very high academic grades, standout drama achievements etc.
I have 2 dcs, Y8 and Y6. While they are both bright and achieve high grades, they're not outstanding. My Y8 dd is learning the guitar - slowly but surely. This is the first time she ever tried anything musical. Ds is learning keyboards but only for fun, nothing formal. Dd plays Netball but her team always looses by a mile. Ds has only just taken up Rugby in Y6. I'm clueless. I don't even know what to bring etc and feel somewhat separate to the other Rugby mum's who've been doing it for years.
Dd is loving Drama within school and has been involved in 2 schools productions so far, but is limited to her roles as she can't sing.
Both my dcs are quite good artists but when dd got to Secondary school she realised there are others much better at it so now feels a bit meh.
Ds is doing lots of singing and drama for a regional Scout production in Feb but it's not high Art, just fun!
Don't get me wrong, I love my dcs beyond measure. They're hard working, kind and very witty to be around. I'm very proud of them. I guess I just sometimes wonder about what I would 'boast' about on SM? 
I think I'm extra sensitive because I had MIL around this weekend who constantly asks me what the dcs 'achievements' are and their hobbies. She talks constantly about her other grand-daughter who spends all her weekends doing Cheerleading competitions and how flexible she is (not my dd's cup of tea at all). I suspect she's having a sly dig about dd. Dd is rather tall and womanly for her age and stands out in that way!
I know logically I'm not in a minority of parents of have well-rounded but not 'stand-out' exceptional children - but sometimes it feels like I am.
Now, I'm annoyed with myself for getting sucked into the idea that everyone has a highly gifted child. I know it's not true really. I need to step away from SM I think!
