Sorry i havnt read the other comments! cos im lazy but i thought id add my 2cents!
My DH has fire red hair (darker in the winter though) and i LOVE it!!!!! he was bleeching it blonde when i first met him so i told him to stop it!! hes always complaining about it and i always say "well i married the wrong guy then if i didnt like it!!! so duh! of course i like it!!" it gives him character!! and noone ever forgets him!!

(being 6ft4 makes him unforgetable as well!!). He has the skip generation gene - his grandad had red hair (so did his great great grandad) and his father has blonde hair and his mother has dark, he was the only 1 of the 3 kids to have red hair (his sis had blonde, he has red and his lil bro has brown), now i have auburn hair and he has red but we ended up with 2 blondes!! (and blue eyed also!!!????) so i dare say that our grandbabies will have red hair
I have always got comments (about Bay and now Astin) such as "UH OH! it looks like his hair is going red!!" to which i answer "so what!!!?? its cute!!!".
Italiah you have 3 ABSOLUTELY GORGOUS!! kids!! red hair or not!!! and i reckon its cool having kids that all look different!! you get to see all the different combinations you can make!

instead of having 3 that look the same!! (not that theres anything wrong with that either!!!)
