About Me



Hello! I’m Katie-Jane

The International Baby Whisperer

My name is Katie-Jane Crosbie and over the last 20 years, I have personally helped hundreds of families find a restful night’s sleep with my proven 3 month old to 6 year old, sleep training routine.

Sleep deprivation can have an adverse affect on your home life, work life, relationship and general well-being, not to mention your child’s erratic sleep patterns can affect their day-time routine creating a vicious circle of family tiredness.

My tried and tested Sleep-training Programme was designed to offer my  knowledge and experience along with my guidance and support, enabling my clients to bring routine, structure and rested nights sleep to their child and their lives. I have tailored the packages to make it flexible and affordable, for clients to choose a package that suits their needs and budget.

I truly am passionate about my work and feel privileged to work parallel with each and every one of my clients, to bring about the positive changes they need.

My Approach & Values

For the past 27 years I have worked with many hundreds of babies from newborn through to 6 years old. I have fulfilled bookings working for clients, including many High Profile families, building an outstanding reputation for my professional working approach and building up extensive, mutually respected client relationships along the way. Many of these clients I am still in contact with to this day and some have developed into lovely friendships.  All have left me with such wonderful memories.

I continue to educate, guide and empower parents on a daily and weekly basis offering many postnatal services under my established name. I have evolved over the latter years to be focusing on my Paediatric Sleep Consultancy Service.  I am constantly being contacted by prospective clients requesting maternity support.  That is what lead me to set up Agency by Katie-Jane. I am excited about the journey I am taking, the team of exceptional Maternity Professionals I have on our books and the top end service that we can provide.
