I drove myself round the bend with my PFBness!!
Everything had to be sterilised including feeding bowls, spoons, the hand blender, medicine equipment (and the sterilizer was sterilised once a month). I did all this until DS1 was 1. Dummies I sterilised until he was 18 months. My entire kichen was Milton'ed to within an inch of it's life.
DS was never allowed in the kitchen until the age of 2 (unless being held/fed)because I worried about floor germs on his hands.
I sterilised his toys every night...and he had loads. Ditto his books!
His clothes were washed separately to mine and DH's, and only in Fairy. He had a number of blankets I used to line his bouncy chair with and if the blanket touched the carpet I changed it immediately.
I regularly steam cleaned the carpets and would only let him lie on the floor on a big blanket that was regularly washed.
I followed Gina to the letter, and refused to let people in if he was sleeping. I would never, ever, let anyone touch his face or hands until he was 6 months.
His food was entirely and meticulously homecooked.
Like Bean, I worried about allergies (although we do have allergies in the family, to be fair)..so I had planned to take him to the local hospital (only 2 mins down the road) and sit in the patients cafe and give him some peanut butter. My plan was scuppered, however, when DH left a stray chocolate covered peanut on the floor and DS1 ate it!! My fury at DH was something to behold that day!! DS1 was fine.
I could go on and on..when I look back now it was beyond ridiculous! DS2 arrived when DS1 was 2 (just turned)...and I simply didn't have the enery to carry on in the way I had done with DS1. Poor DS2 has been neglected in comparison..I didn't change his bouncy chair blanket for a fortnight! His clothes were washed with ours and he had jars!! And no Gina 
Aside from being a very bad eater he seems to be fine for all his neglect
