Caroline Smith BSc.RD - AP Paediatric Dietitian
I am an Advanced Practice Paediatric Dietitian with 15 years’ experience in the NHS. I earned my Degree in Human Nutrition and Dietetics from King’s College London in 2007. Starting in elderly care and the stroke unit at a North London District General Hospital, I quickly specialised in Paediatrics, moving to a specialist post at Kingston Hospital within a year of qualifying. I completed Masters level qualifications in Paediatric dietetics while managing a diverse paediatric caseload.
In 2010, I moved to a clinical specialist post at the Royal Brompton Hospital in central London, focusing on managing children with cystic fibrosis and complex heart and lung conditions. In 2012, I returned to Belfast, working within the Northern and Southern trust across various specialties in paediatrics, including inpatients, general clinics, and allergy-focused outpatient care.
Since 2015, I’ve specialised in Type 1 Diabetes, supporting children and their families from diagnosis, conducting group education sessions, and optimizing diabetes management through diet.
From March 2020, I’ve been in my current role, focusing on infants and children with cow’s milk protein allergy and other food allergies, providing support, advice, and individualised action plans.
I’ve also worked extensively with families managing selective eating in toddlers, assessing nutrition status, and supporting behavior management for optimal growth. Additionally, I’ve focused on infants struggling to gain weight, ensuring their nutritional needs are met for development.
I enjoy researching, writing, and have published articles in Nutrition magazines and presented a poster on weight management in children with type 1 diabetes. Recently, I’ve begun offering private services in allergy management and am excited to join the 1:1 dietitian team to expand paediatric care further.
Personally, I’m married with three school-aged children and two cats. I relish good food, diving into a good book, exploring Northern Ireland’s coast and the Lake District, where my in-laws live, and spending quality time with friends.

I am Abimbola (Abby) Olu-Sholanke (B.Sc Hons, MSc, RD, mBDA, HCPC), a Registered Dietitian with over 15 years of experience in hospital and private practice. My journey began with a degree in Nutrition and Dietetics from the University of Ibadan (BSc.

I’ve worked with diverse clients across corporate, private, and public sectors, advocating for nutrition through radio shows and other media features.
Through this journey, I’ve developed expertise in community/group nutrition, clinical weight management, hypertension and type 2 diabetes support, heart health, and more. I’m actively engaged in the community, leading a wellness group and supporting individuals during the challenging times of the COVID lockdown.
As a freelance dietitian based in Belfast, my specialties encompass hypertension, type 2 diabetes, gut health, clinical weight management, nutritional therapy, geriatric nutrition, functional nutrition, personalized recipes, and support for disordered eating. My passion lies in guiding and supporting clients towards their health goals, aiming for a better quality of life.
Outside work, I find relaxation in watching movies with family, enjoying music, leisurely walks with my partner, or even indulging in a power nap. I have a love for travel, speak English, French, and Yoruba, and aspire to explore more of the world while picking up golf along the way.
