I suppose that when you have both an aging parent and a just-walking toddler, the idea of owning a double-buggy starts looking attractive even if you don't have a second child.
But even though her legs tire easily and she needs to rest every 100 metres or so, my mum is far too proud to try a walking frame - she has only accepted the advantages of using a walking stick in the last year or so.
However, her current spell in hospital has made it clear that, at least while she's rendered weak from a combination of an infection and it's affect on her various other ailments, a walking frame is a pretty handy mobility aid.
It also makes for a fab toy. TLM's daily visits to her Poh Poh had stopped being a novelty (especially when I wouldn't let her play with the power points and the monitoring equipment), but since yesterday this grown-ups version of a walking trolley has been her favourite plaything. One time she even grabbed it right off my mum, leaving her standing in the middle of the lift foyer, and pushed it around the waxed floors until it was needed for a trip to the loo.
