sorry if this is tmi for some but if I can't ask here where can I? to what extent do dds need to clean all their little creases etc? I'm afraid mine kind of give themselves a bit of a scrub with a flannel. (trying really hard to work out how to word this....) whereas when I'm having a shower myself I'll have quite a rummage - and make sure water has sluiced its way through all the bits and pieces. I'm worried that the flannel business isn;t really doing its job...
