My 16-year old sister (only sister), is my MOH, and I definitely wouldn't have it any other way. The bridesmaids are all cousins and groom's sisters, and my long time best friend.
They are all very excited and I think it's a great bridal party -- however they are all asking me what to do about my sister and planning a bachelorette party, having drinks, etc. I have told all of them that my sister knows she won't be able to make it to all of it, but it's important to all of us that she is included in something somehow.
I am nervous to tell the other bridesmaids what to do about my sister and a bachelorette party, but I am not really sure who now "makes a plan" for that, as it would usually be MOH's "responsibility"?
