Do you also have this attitude to medicine, non-organic food, pesticides, pollution, caffeine? And also believe in women not over a certain age or BMI being pregnant? They all have risks and can affect the fetal development.
That's a daft argument. Of course you minimise your exposure as far as is reasonable. Eat well, don't smoke or drink, avoid known toxins, exercise and stay healthy.
And yes I thought of all those things in pregnancy. I only use BPA and phthalate free plastic containers. My drink bottle is glass.
I buy organic fruit and veg where I can afford it anyway and grow a lot, but in pregnancy did that far more. I only use the chemical free cleaners in my house.
Absolutely would not have had caffeine in pregnancy. Really sensible about refined sugars, ate wholegrains, as much from scratch cooking as possible. 7 fruit and veg a day.
Organic fruit and veg maybe out if the reach of some budgets but the rest is all easy to do. I honestly I do think you should be a reasonable weight and eat really well in pregnancy.
Whatever goes in your body is what feeds your baby. If you wouldn't want them to eat that as a weaning baby and toddler then don't feed it them as a foetus.
You get one shot at growing them and it only takes a few months, why not just give it your all for that time?
