Kim Kardashian used a surrogate to carry her third and fourth children, Chicago and Psalm.

I watched the movie Private Life at the weekend, a brilliant film on Netflix about the complications of assisted parenthood. Rachel and Richard, played by Kathryn Hahn and Paul Giamatti, are desperate to have a much-longed-for child. 

This poignant, sometimes hilarious comedy drama makes astute yet non-judgmental observations about the deep biological urge to have a child and the lengths to which a couple failing at expensive $10,000- a-pop IVF may go.
