I have a shower every day, before work, sometimes twice if I've been to the gym or if we're on holiday / going out. I probably make sure the younger kids get a bath about 5 times a week and my teenage daughter has a shower every day.
SIL was outraged at this and says that she only typically has a bath or a shower once a week! She says that she has a wash every day with a face cloth (including her bottom :O - with a face cloth!!).
Maybe it's me who's odd but I was staggered at this
