You are soooo right! It's so lonely. I thought I would have a kid and get to join the exclusive mommy/ parent club and instead I'm still standing on the outskirts. My husband is wonderfully supportive and is willing to devote any resources on the planet to ensuring that she gets the enrichment/ stimulation she needs to stay sane (he hated school because he wasnt challenged). His parents watch our daughter while I work 3 days a week and they were the ones who first commented about her "condition"

.
Every path has it's own advantages - I got to join the momy club because I had 'zero' idea of what normal was, and was blissfully ignorant. Of course when school started I got my payback. On the whole I'm sad that you feel lonely, but I'm jealous that you know 'right away.' Sooner or later, many of these kids 'out' us - and we can both be grateful that our children both did that.
Sounds like your DH and in-laws are on board, and that is also worth more then a whole subdivision full of mommy-club moms.
I'm really glad to hear that you are keeping notes.
Enjoy the board, and join Connecticut Association of Gifted, ok?
