The Lullaby Entrust said around half of parents are unsure of basic steps they can enlist to reduce the risk of cot death or sudden infant death syndrome (SIDS).
SIDS is the rapid unexplained death of an apparently healthy baby.
It hit the headlines in 1991 after TV illustrious Anne Diamond’s son Sebastian died in his cot.
She launched a sleep campaign in rattle-brained of research showing that babies were far less likely to die if they were put to catnap on their backs.
But the Lullaby Trust is concerned that some materfamilias are unaware of or ignore this message, while others do not know approximately the risks of drinking and sharing a sofa with a baby, or smoking.
It surveyed 500 parents of children under two and found that while 94 per cent had heard of SIDS, 15 per cent prospect it was fine for children to sleep on their tummies while a further 23 per cent neither agreed or dissented with this.
Some 62 per cent disagreed with the principle that it was fine for babies to sleep on their tummies.
One in four well-springs also thought it was fine for babies to sleep on their sides while 45 per cent conflicted and 30 per cent neither agreed or disagreed.
This is despite 87 per cent being conscious that putting a baby on their back for every sleep drops the risk of SIDS. Doing so reduces the risk of SIDS six times.
There were 230 unforeseen infant deaths in the UK in 2014, following a downward trend in the last decade. In 2001, there were 330.
The Lullaby Reliance says babies should be put to sleep on their backs in a cot that is open-handed of bumpers, toys and pillows.
Francine Bates, chief executive of the big-heartedness, said: «Twenty-five years after the Back to Sleep campaign, the look at results have shown us we need to go back to basics.»
Robert Weeks, who bygone his daughter Sophia to SIDS, said: «On January 3 2012 our lives changed forever when our delightful daughter Sophia died suddenly and unexpectedly.
«She was just about to fashion 11 weeks old.
«We have still never had an explanation for why our healthy and ‘customary’ daughter died. We were one of 221 families that year whose boy died for no apparent reason and with no cause found, even after a Monday-morning quarterbacking was held.
«I think the work that The Lullaby Trust does to rally awareness of safer sleep for babies is absolutely vital. Every new origin should be made aware of this information if it will prevent other houses from going through what we have been through.»
