What parents say

★★★★★

We wanted a dietitian to help with our son, Harry. Harry has sensory problems and would only eat about 5 different foods at the time when we got in touch with Kate. Kate was thorough in her assessment of his diet and advised on what we needed to do to supplement his diet, so he didn’t miss out on any goodness. She also gave us recommendations on ways to encourage Harry to try new foods.
We still have work to do but I already can see a big difference in Harry’s response and willingness to try new foods.
I am also very reassured now that he is getting all the goodness he needs, despite having a limited variety in his diet.

Testimonials

Hear from our satisfied customers who have experienced the quality and value of our services.

We were recommended to book to speak with Ruth about our six-month-old daughter’s Cow’s Milk Protein Allergy.
Ruth was very forthcoming with information and straightforward guidance to support us in our weaning journey and shared a number of valuable resources with us after the session for reference.
We now feel well equipped and empowered to start out with weaning in a safe and manageable way.
 
Thank you!

Casey – Mum to Alex

It was quick and easy to get an appointment, which was appreciated, and Ruth was very helpful before booking to ensure it would be the right fit for me. Meeting via Zoom was also very convenient as it allowed me to fit the appointment into my working day! When discussing my son’s dietary needs and food allergies, Ruth was very reassuring and helped me to understand what he needed and gave pointers for further support and advice.
