Ofcom received 752 complaints from viewers about Channel 4's 'Bringing Up Baby', accusing the programme makers of 'child abuse' by using outdated and unethical infant care techniques.
The programme assigned six different families to three different childcare mentors who followed care manuals from the 1950s, 1960s and 1970s - Truby King's Feeding and Care of Baby, Dr Spock's Baby and Childcare and Jean Liedloff's The Continuum Concept.
Last week Ofcom found that the four-part series did not breach broadcasting rules.
Ofcom said that Channel 4 had consulted a range of experts prior to filming and the 'broadcaster gave careful and appropriate consideration to the potential impact of the methods used on the infants and sought relevant independent advice. We have seen no evidence to suggest that due care was not taken over the physical and emotional welfare of the children, or that they were caused unnecessary distress or anxiety.'
It said the methods were used 'in context' and their pros and cons were 'explored'.
However, Ofcom said it was unclear from the programme whether or not Claire Verity - who advocated the strict Truby King method - had professional qualifications and that it would have been 'preferable' if she had not been referred to as a maternity nurse in the programme.
Some viewers had complained that the term implied that Ms Verity had qualifications.
Ofcom said, 'It is clear in cases such as these, where there is the potential for harm, broadcasters should be careful when using terms which may imply participants have medical qualifications or professional status.'
