8 weeks is alright to have your booking in appointment. Its a shame there arent any leaflets givento you really, you're sensible enough to find out but I bet there are plenty of people who wouldnt. Basically you need to avoid food poisoning so no shell fish, no runny eggs, no pate, avoid certain cheeses (not sure which, I dont eat cheese) avoid caffine and alcohol. ummmm, I cant think of anything else, I think my baby is eating my brain cells!
