The Ministry of Health is being urged to make it clear that babies under the age of six months are at risk of death when they share a bed with adults and siblings.
Wellington Coroner Garry Evans has included the recommendation in findings from an inquest held last year.
Mr Evans says the safest place is a cot beside the parents' bed.
The ministry says it will study the recommendation, but differences remain of opinion and parents can hold conflicting views.
