As a parent (maybe more so as a mother) you seem to cop your fair amount of poo, pee, vomit, snot, water, food, juice etc, as a daily occurrence. It's just part and parcel of being a parent (or even a carer, Aunty etc).
Yesterday I had already had poo up to my elbows, because my fourteen month old won't lay still on the change table and food wiped over my shirt. So when I offered James a drink of water, he took a mouthful and spat it out (charming I know) I ended up with the lot all over my arms and second shirt. Five minutes before we were leaving home, of course.
I said to him, "why is it I always seem to get your poo, pee, food, spit all over me?" His reply was a little kiss right on my lips, no teeth or anything. The sweetest kiss I've ever had. I suppose I can take a little bit of my son's bodily fluids if the rewards are always so sweet.
