Claire revels in her moniker of 'Cruella de Vil' of the baby world and claims that, even though her methods are strict, she can guarantee 100% success. The method she has devised is based on Truby King's routine, which she learnt about during her maternity nurse training. Claire often has a clash of opinion with her clients, especially on her rule of not picking up and cuddling a baby too much. She says that breakthrough happens when suddenly the mothers see that their baby is no longer 'unmanageable'and that they have their lives back – it's then, she says, that they accept she has been right all along.
