Like the others have said, it's so important to do whatever feels right for you. I just had DH for our first and that's who it will be this time around - besides the MW/Dr of course. I felt like if I had my mum I had to ask MIL and there was no way I wanted her there, nice though she is, we just don't have that sort of relationship. Given the unpredictability of when things will happen, there's no guarantee of my mum getting there as she lives too far away anyway. DH was great, as were the MW, and like someone else said, once I hit 'the zone' I barely noticed anyone. Do what's right for you.
