Telling Family

Roblyn
I'm single and 12 weeks currently. The dad is currently around and will help financially for a little while after baby is born but will go back to his home country soon after baby is born. 
I have 2 brothers. One is more the "do whatever you like, it doesn't affect me" kind of guy. The other is the " I don't want to have to save you when you get into trouble..." kind of brother. Ive already told the more lax brother but I'm scared to tell my more strict/more likely to yell brother. 
Do you have anyone in your family like that? How did you deal with telling them?
