Supernanny Jo Frost - famous for taming toddlers on television - has turned her attention to newborns.
But that doesn't mean 37-year- old Frost, who has no children nor a current partner, can feel her own biological clock ticking.
And she says she doesn't have to be a mother to be an expert on infants.
In her new book Confident Baby Care, Frost enters the breastfeeding debate, saying women should not be "ridiculed" for choosing to bottle feed.
Frost says she supports breastfeeding, "but not to the extent of making bottle-feeding parents feel they should be banished off the face of the earth".
Speaking from Florida, where she's filming the fourth American season of Supernanny, Frost says generations have been raised on formula and turned out "just fine".
"It's important to have a mother of sound state of mind (if she is happier bottle-feeding), rather than an unhappy mother who is ridiculed and judged," says Frost.
Confident Baby Care recommends breastfeeding mothers consider introducing a formula feed between six weeks and three months - against the Plunket ideal of exclusive breastfeeding at this age - as formula will fill babies up more so they sleep longer.
Frost's book gives advice on a baby's first year including what gear to buy, milestones and hints on settling.
She says the book is like having "your very own live-in me".
