Coumarin Not defending him so much as defending his wife & her ability to form her own opinion/ideas about what she listens to during labour.
Women on mumsnet will tell you that we all have the right to do what feels right for us/our families. Time & time again expectant mums are encouraged to make a plan for labour, music & distraction being top of the lists. Yet, when it comes to RW & his wife, she is being perceived as not having a choice about what music she listens to, or how her labour progresses, or what distraction techniques she chooses to use.
This is highly insulting to Robbie, painting him as some controlling guy who takes over because he likes the limelight. And paints her as some submissive, terrified woman who feels like she must submit to keep him sweet & doesn't have a say in how her labour goes.
I find it highly insulting that some women find another woman not capable of making choices they themselves wouldn't make, and then suggesting that she can't be enjoying it because they wouldn't do it/enjoy it.
The end of it is...she obviously loves him. They have a relationship where humour factors in a big way, I would imagine. They have been planning this day for at least as long as she has been pregnant. They both decided how it would go. She may have chosen to listen to his music because...oh I dunno....she LIKES his music? Just maybe..
