Some self-described infant sleep experts are giving advice that could put babies at risk of serious harm and even death, medical professionals have told a BBC investigation.
We secretly filmed one of them advising our reporter to put a newborn to sleep on its front, a practice proven to significantly increase the risk of sudden infant death syndrome (Sids).
The NHS advises to "always place your baby on their back to sleep" in their own sleep space, like a cot, for the first 12 months to reduce the risk of Sids. The mattress should be firm, flat and waterproof.
A second self-defined expert recommended placing towels in the infant's cot - a practice The Lullaby Trust, a baby safety charity, says also increases the risk of Sids and "accidental death".
Medical professionals who watched our undercover footage said moments had left them feeling "sick" and "horrified".
