Never had this with tommy so I don't know if it's normal or not, Charlie is obsessed with showers and baths, it use to be just a shower in the morning, now quite literally he's had two showers and a bath today, shower this morning, then one before bed, then decided he was finished in the shower and ran straight to the bath and spent 20 mind in there!
He will ask to shower more as well, quite often after he's done a wee or poo.
I just seems a bit odd?
