I'm going to go against the grain (just a little bit). I was the opposite and wanted to show ds off when he was born. It was very difficult for me to understand when my best friend said she didn't want me to come around when her baby was born 6 months later. She only allowed family.
It was even harder to understand as she was at the birth of my ds, and his godmother.
I tried really hard to see things from her perspective and never told her how hurt I felt, as it was her baby's birth and I didn't want to taint it.
I waited a whole 3 weeks for her to ring me and tell me that I could come and meet her ds. I had made peace with that, but when I finally went to see her, it turned out that every man and his dog had been to visit her and she had kept me waiting 3 weeks.
It broke my heart as I thought of us as sisters, (which she did too and I have no family near me) but when there was an important time in her life, she very clearly shunted me into the 'friends' category.
Sadly, I've never come to terms with it. I know it sounds selfish, but it really really hurt me. I've never told her any of this, as that would be completely selfish, but our relationship is not the same. Even though we have ds's that are the same age, we now never see each other anymore, and she is my ds's godmother in name only (another thing I am very sad about.)
All I would say, is that I really, really understand that it is your time and your decision, but it won't hurt to take a few minutes out and think about the people you are asking to stay away. If you can live with that (as my friend could) then that is fine.
I suspect that if she were to ever find out how I felt, she will be horrified, but I don't intend for that to happen.
Sorry, it's turned into a novel. Just thought I'd give you a different perspective.
