Telling family and friends,

Hey guys, I'm 6+2 weeks, getting very hard around the festive time not to tell people were pregnant, I'm really worried about telling people to early tho! Even if we wait till Xmas eve will only be 8 weeks, I'm abit of a drinker so family will guess if I'm not drinking Xmas! Haven't even told my mum yet as i have a big family so if I tell one I have to tell all my sisters aswell, we're all very close and it's already hard! :/ advice? Who's telling who when? X
