Anyone else annoyed with name suggestions?

M
I like to have a mental list of names and then decide a day or two after baby is born and we get to spend some time with them. It makes the naming process really intimate. 
My SIL keeps asking me what I'm thinking of for names and I just don't even want suggestions or input on what I choose. I just can't stand the opinions and "advice" and suggestions. 
SIL isn't mean or anything, just overly enthusiastic that I'm having a girl (she has a girl) and it drives me bananas when people get involved in what I consider intimate decisions between myself and my husband.  
So, I politely told her (again) that we have a list of names we are considering and will meet the baby and decide on a name and let her know when we have chosen. Sigh. 
Anyone else going through this?
