Yeah I agree I can see why someone would want their mum! My mum is going to be there when I go into labour because she will tell me to get on with it!! I get really pathetic around OH when I feel ill/tired etc, whereas my mum has a knack of making me snap out of it, so she will be good when I think I can't do it anymore! Lol.
If my mum was the same as the one last night though I would def not have her there, from a purely selfish point of you the mum should be there to help you, you shouldn't have to 'put on a brave face' while you're in labour x
