If, like me, you used to be able to shop for hours without even the merest hint of exhaustion, but are finding the fact that this is no longer the case but it catching you completely unawares, you could do worse than realise that mamas and papas on regents street has a cafe upstairs, has free wifi and even serves decaf twinings tea.
Of course, you might have listened to your husband weeks ago and accepted your new limitations. Sadly, not me. I keep on pretending I’m not pregnant and can keep on as before. It’s not the case though. Hence the decaf tea.
