Thoughts?

Ill be 25 weeks this sunday! Im due December 15th. My sister who is also my best friend is due October 21st. My boyfriends aunt was wanting to throw me a babyshower but rly hasnt said much, it really doesnt matter to me who throws or If i throw it myself...(can i do that lol?) But really whats a good date to throw a babyshower? And how long should i give myself to plan if i do indeed to it myself? My only concerns are I want my sister there and I know with having a newborn can be iffy. Thats right at the end of october and then november well my cousins baby is due and its thanksgiving and then Bam december is when im due, so I am entirely unsure if I should completely avoid the holidays and just do it for the beginning of october? Help.. lol
