Nice to see you again :)
Can't help with the spiders, Barbeasty, but I wonder if just ignoring the whole thing might help?
Greensnail - you just made me snort-out-loud at my desk with your dinner-in-a-cup description
....I can imagine Mia doing something exactly like that 
Goodname - ds went through something similar at about this age. iirc (its a bit hazy) we used a combination of showers, not bathing, flannel-baths and the occasional screaming-fit-nightmare-but-we-need-to-get-him-clean bath. The my aunt gave ds a brilliant set of boats, submarines and people for xmas and suddenly the whole thing just stopped.
Madamefreckle - waterproof bibs until she gets the hang of it?
WWISA - they will grow out of it. Honestly, they really will. But it does sound very wearing for you, in the meantime....sending you some good sleep vibes for the interim....maybe you need some industrial-strength ear-plugs, and then let dh do some of the night-time getups?
Mia has started to become much easier since she learnt to walk. She can still be very clingy if she's tired (or just feels clingy!) but I'm still in shock every time she toddles off to go and explore another something regardless of what I'm up to....its such a relief! The best moment is after we get her up every morning, where she has to 'remember' that she can walk all over again...she falls over every 3 or 4 steps along the landing until she gets her balance, then she's fine.... :)
