Awww, nevermind AJP, I've a few more grey hairs too since my third was born... I've read that it can happen with a mineral deficiency... something weird like copper (?) as well as genetics. Anyhow, I'm deciding to go a little lighter with my next hair colouring... and don't worry... I had greys at 28 too... however I'm a bit older than you and can report that as an "up side" my hair on other body parts eg legs is getting sparcer as I age... so that's a welcome development anyhow
