For DD1's birth, it was just assumed that DH and my mum would be with me. I don't have sisters or any really close female friends, and DH is truly my best mate as well as my husband so I wanted him there more than anything. Because I was induced, I was in hospital for a couple of days waiting for things to start moving so mum didn't get there until I was well and truly in labour - I remember DH asking me if I wanted him to go pick my mum up (Dad had gone away for the weekend and mum didn't have the car), and I started yelling at him to 'tell her to get a ****ing taxi, you are NOT leaving me now!'
It was so funny because I'm not really *that* close to my mum, but in the throes of labour I needed my mummy lol, I felt like a little girl with a scraped knee!

The second time around it was just me and DH - I didn't need my mum at all and DH was more than adequate support for me. It was actually nice to not have my mum fluttering around and panicking about seeing me in pain - the birth went smoother and DH and I enjoyed our private time with the newborn.

Good luck!! I hope whoever you choose is/are the best support for you
