With a background in fashion production (I first met her on a Vogue shoot), Barrett, 41, has spent over a decade working with people such as Mario Testino, so she’s firm, fair and, most importantly, used to tight schedules and last-minute requests. Since Confident Dad launched 12 months ago she has balanced being welded to her phone ‘making things happen’ on fashion shoots (a job she now does part-time) with giving advice to new parents. I don’t know how she does it. In fact, I do. Her business partner, Barrera, 38, is a qualified Montessori nursery teacher with 17 years’ nannying experience and a no-nonsense approach. Both women have two young children. They don’t get involved with any legal or moral aspects of surrogacy, but for £350 they offer a two-hour crash course in caring for a baby, with the possibility of further one-hour follow-up sessions at £150. ‘You produce the baby and we’ll help produce the rest,’ says Barrett breezily. The ultimate in peace of mind comes in the form of the most comprehensive package, which will guide you through choosing a maternity nurse from a recommended list to seeing your child take its first steps.
