New guidance from the Royal College of Obstetricians and Gynaecologists claims there is not enough information about potential risks to unborn children from chemicals found in many household products including moisturisers and shower gel.
It has advised pregnant women to "play it safe" and avoid using the products. But the advice has been criticised by other experts for being unhelpful and causing unnecessary worry.
GP Dr Arun Ghosh says that the potential risk to health from household chemicals discussed in the research paper remains unproven, and that pregnant women and new mothers should not change their habits.
He says that the best advice is for pregnant women to use organic products where possible, and to be aware of the research that is available.
