I have a "Mum Tum". My first step is admitting it. Apparently, some people with means schedule tummy tucks after giving birth. Before I had children, I thought this was ludicrous. Do a few sits ups. Cut down on the biscuits. Get out there and walk. No need for surgery, I thought with judgmental delusion.
Mind you, as I write this, I'm finishing off a glass of wine and just enjoyed a home made brownie. Perhaps I have ordinary "Fat Tum" rather than "Mum Tum" and am just in denial?
