  • “Chana Masala Recipe - the recipe was so empowering for me. I have had trouble reading recipes... baby brain! Felt like sudoku at times! But yours was relaxed cooking for me. That's the first time I enjoyed cooking since I had Ben.”

  • Sarah has been a valuable support in navigating the challenges of introducing solid foods to our allergic twin babies. Her knowledge, encouragement, and allergy-friendly recipes have provided helpful insights. This journey has not been the easiest and we so appreciate your help Sarah.

  • Sarah joined me as a guest speaker for one of my Becoming Mum workshops. She is such a wealth of knowledge and I feel so lucky to have had her come and share her wisdom with the mums in my course. She spoke about postpartum nutrition and also provided them with a really comprehensive handout to take home with them. Sarah has such a calming and approachable vibe to her which made the mums feel super comfortable. I am so looking forward to having Sarah join us for many more workshops in the future. Really highly recommend reaching out for any personal nutrition needs/goals you may have.

  • The hour I spent with Sarah going over my prenatal nutrition made my third pregnancy the most healthy, energetic, and iron filled one of all. With my first two, I was constantly fighting fatigue and had to go onto iron supplements pretty early. For my third, I didn’t have to go on iron supplements at all and my fatigue was minimal in comparison. I’m constantly sending people her way for this and all things nutrition for starting solids with babies! Love what you do!!
