Ugh I cannot imagine anything worse....my body my baby my damn rules for the birth
I've said it on another post...id rather walk through a cactus field covered in lemon juice before I'd have my mother at either of my births
I am probably being unreasonable but I do often question the arrogance of mothers who insist on attending (not the ones that the daughter wants there...i don't get it but it's personal choice and up to the labouring woman)
It makes it all about them...its "their right"...not controlling at all is it ? 
My Dmum knew Better than to suggest it tbh (even 2.5 hours away with not being told when I was going in for C section she STILL managed to ring the nurses station 3 times while I was in recovery ...imagine what she would have been like actually there !!)
Trigger to follow
I also query...with DS2 things went badly wrong very very fast...which resulted in me being run at full speed unconscious in a wheelchair into the delivery suite with 3 anaesthetists two doctors and two midwives desperately trying to get lines in to get him out, conversations that left Exdh in zero doubt out lives were in imminent danger and a fun experience in ICU for me , NICU for ds2, lumbar punctures and incubators the whole shebang)
Who in hell wants to see or be involved in that?
End trigger
Your body your rules....anyone who argues needs to seriously review their entitlement
