My mum used to call those all-in-one sleep suits "wombles" in some bizarre attempt to get me, my brother and my sister to wear them. ("The wombles" was a big tv show for kids at the time). I never realised that there was any other name for them until the tender age of 22 when I called one a womble infront of a large group of friends... Seven years later, I still haven't heard the end of it
