I had planned for my DH, SIL and MIL to be there. I was present at 3 of my SIL's 4 kids births - and it was very special to me. So I really wanted to show my gratitude to her (and let her experience what she gave me). My MIL was invited as my own Mother has passed. I'm a firm believer in village birthing where the people who are going to be important in the child's life are present at his birth - as it really helps the bond begin straight away.

I certainly found this was the case.

Unfortunately we were sent to a different hospital than we planned on and they wouldn't allow 3 people in with me - so MIL graciously offered to sit out. My DH gave his sister the honour of cutting my DS's cord - which meant soooo much to her.

I really wouldn't have changed a thing.

Having said all this - you must do what you're comfortable doing. I'm not an overly modest person, so the whole 'naked in front of others' thing didn't bother me and I'm quite close with my SIL and MIL, so it felt quite natural. That wouldn't be the case for everyone.

Good luck!
