ophelia conant had managed to crawl backwards through a gap in the cot at her home in holmer green , buckinghamshire , but was left hanging mid air by her neck .
the 19-month-old was only saved when her mother , louise conant , happened to be watching the incident unfold on a baby monitor .
days later a second toddler was found dangling from the £ 450 bed with his forehead jammed against the horizontal handrail .
