Jesus if it wasn't for epidurals I'd never have even considered getting pregnant.
Greatest invention in earth. You don't get a medal for "most pain bravely endured" .
Also, you have to be at least 4cm dilated (10 hellish hours for me both times!) before getting one or it slows labour down to dangerous levels. I don't care where she gave birth, you don't just walk into the hospital reception and airily demand an epidural now please, quick smart, please and thank you.
Let's not go crazy with making up stuff to suit some narrative of her being selfish. She may or may not be but it makes me very uncomfortable when people bring the kids into it. In fact, I've always thought she had quite a close relationship with her daughter. As close as a you can have with a moody teen girl who's embarrassed by you.
But there is no way she didn't labour just like the rest of us unscheduled folks, and its unkind to imply she's too posh and selfish to even endure a contraction.
