Right, I'm 5 weeks and 1 day, have had the congratulations from the GP, booked a midwife, got my iodine prescription, been taking folate for a while, have watched Michael Mosley on leafy green veg & listened to The First 1000 Days on fish oil... I'm exercising appropriately (not too hard, no cycling outdoors), eating a healthily Mediterranean diet (avoiding too many servings of fish/livers potentially containing VitA or mercury), not having too much caffeine, avoiding nasty chemicals in laboratories and pesticides when gardening. Handwashing appropriately after gardening, have tetanus vaccine and Toxoplasma antibodies already. Routine scans and tests are all booked in, vaccinations all up to date (pertussis is given in the 3rd trimester here). We're thinking about what needs doing to the house to make it habitable for a baby (rather than a cold-adapted adult with 5 jumpers on). We've got finances under control. We've got a car, we live sufficient distance for parents/inlaws not to be a pain in the bum, we have good sensible friends who have kids who can provide support.
But so far it all seems puzzlingly easy. I've no doubt that will change in about 35 weeks' time, if not rather sooner, like in about a week or two, when morning sickness kicks in 
Anyone want to suggest other changes i should be making?
Stopping using tinned food and/or plastic containers for food storage?
Eat yet more broccoli and chinese greens?
or just getting on with normal life and not spending hours every day on Mumsnet?
*Iodine is a standard thing where I am, and maternity is midwife-led here.
