Ya know, its amaaaaazing anyone got through pregnancy in tact back in the day - 30 years ago smoking and drinking and no scanning occurred and whilst I think that you should minimise risk to yer lil un, kids are less hardy now because we avoid EVERYTHING and they don't build up a hardy immune system.
Our bodies are FAB at processing stuff that shouldn't be there - look how fast kids get ill and recover - and to an extent they teach us whats what - like going off coffee etc.
Basically I think, keep risk low but live your life so whilst I am not smoking and doing naughty things nor am I getting drunk or swigging espresso muchly (apart from anything else, it would make me sick) I shall be seeing to my puddy tats, eating peanuts and shop bought pate and living my life. The pate/egg risks apply to the non pregnant too, just the consequences are potentially worse for us I think.
gee whizz that was a bit ranty, I dunno whats up with me today....what's in cheerios???
