The nappy science gang who took on the NHS

It's best to wash nappies in non-biological detergent, right? Wrong, as a citizen science project discovered when they challenged NHS advice on the subject

"I appreciate your evidence-based approach." I said recently, in a heated discussion about washing nappies, "But while the NHS recommends using non-bio detergents on baby clothes, you aren't likely to convince the whole country to change its view." "Yeah," said a colleague, "getting the NHS to change their views on anything is like trying to get a baby to sleep on demand."

"Change has to start somewhere," replied our conversation partner.
