'Here's a question. Why do people have kids? I'm almost nine months pregnant and still I don't know. People tell me I’ll understand when I hold our baby in my arms for the first time. But I feel cheated, shouldn’t I know by now?'

Kate is 30, married and nine months pregnant mostly by her own choosing, if you don't count the interference from that damn Mother Nature.

Perfectly ordinary circumstances, so why is she freaking out so publicly about becoming a mum? Surrounded by 'professional mothers' and mothers-to-be who are only too happy to sacrifice brie and wine for piles and nappies, Kate is desperately out of her depth. Is that really all she has to look forward to when she joins the Dark Side?

Then Kate meets fellow cynical mothers-to-be, Evie and Chloe, at pregnancy yoga or 'Proga' as the in crowd call it and things start to look up. Suddenly spa days and wine, albeit non-alcoholic, are back on the agenda and it's not long before the girls are affirming that old adage, 'trouble always comes in threes…'
