 Before being broadcast, the program received bad publicity as it was seen to be immoral to allow inexperienced teenagers to look after real babies.However, the BBC assured viewers that the parents of the babies had given consent, and that a nanny was on hand at all times to intervene if need be.In actuality, when the show aired in the UK, few parents intervened even when their babies were extremely upset, and the nannies gave controversial advice, including letting babies "cry it out".
