SMA Launches Infant Gut Health Guide

Introduction

• New research from SMA® Nutrition reveals that 82% of parents of under 5s search online at least a few times a month for topics relating to baby gut health, highlighting the strong demand for clear and accessible information during early childhood.
• 60% of parents of under 5s say modern parents face more pressure than ever before, while nearly half of British adults (48%) say there is not enough open conversation or education around infant gut health.
• SMA® Nutrition launches The Infant Gut Health Journey, a new guide bringing together expert information on the gut microbiome, feeding, the gut-brain connection and when to seek advice.
• The findings reinforce why the first 1,000 days matter for infant gut health. This is a key window when a baby’s gut microbiome is still developing, and early feeding choices can help shape digestion, immunity and healthy growth.
• As part of the guide, Annabel Karmel MBE unveils new gut-friendly weaning and toddler recipes, including her Rainbow Veggie Orzo and Baby Baked Beans.

LONDON, Wednesday 15 July 2026 – New research from SMA® Nutrition reveals that 82% of parents of under-5s search online at least a few times a month for reassurance about baby poo, digestion or tummy discomfort.

In response, SMA® Nutrition is launching The Infant Gut Health Journey, an expert-led guide designed to help parents understand the vital, yet often overlooked, role that gut health plays in a baby's early development. Focusing on the critical first 1,000 days of life, the guide highlights why nurturing infant gut health is so important. Bringing science to life, the guide features insights from Dr Caroline Childs, Lecturer in Nutritional Sciences at the University of Southampton, alongside delicious new gut-friendly weaning and toddler recipes created by the UK’s No.1 baby and children's cookery author Annabel Karmel MBE.

Parents look for reassurance, but not enough know where gut health fits in

From baby poo and reflux to wind and tummy discomfort, the findings show how often parents look for reassurance as they navigate their baby’s early health and try to understand when it’s time to ask the experts for advice.

Nearly half of British adults (48%) say there isn’t enough open conversation or education around infant gut health, while 60% of parents of under-5s say parenting feels more pressured than ever.

While 73% of British adults say infant gut health is a very important part of a baby’s overall wellbeing, many parents are still looking for practical guidance on what that means day to day. Crying and fussiness topped the list of first-year health anxieties for parents of under-5s at 42%, followed by sleep (33%) and feeding (30%).

Why the first 1,000 days matter for good gut health

Together, the findings highlight why the first 1,000 days matter for infant gut health: this is a period of rapid growth and development, when a baby’s gut microbiome is still forming and feeding choices can help shape early experiences around digestion, food variety and comfort.

Parents’ questions are often rooted in common first year experiences, with over a third of parents of under 5s saying their baby experienced constipation (37%), general tummy discomfort (36%), reflux or spitting up (36%) or colic (35%). When seeking advice, parents most often turn to healthcare professionals, as well as close family, baby and nutrition brand websites, and official medical or public health sources.

The Infant Gut Health Journey has been developed to turn the complex topic of gut microbiome development into clear, practical guidance that parents can use every day. The digital resource breaks down why the first 1,000 days are so crucial to long-term gut health, including how the microbiome develops, how it’s shaped by feeding choices and food variety, and the role it can play in digestive health and immune function. It also includes guidance on when to seek advice from a healthcare professional.

Dr Caroline Childs, Lecturer in Nutritional Sciences at the University of Southampton and a leading expert in the gut microbiome and immune system, said: “A baby’s gut does much more than digest food — it also plays an important role in supporting the immune system. Early life is a key window for the gut microbiome to develop, which is still overlooked, despite its role in supporting good gut health into adulthood. Feeding is one of the most important influences during that time. Parents do not need every scientific detail; they need clear, evidence-based guidance that helps them understand what may support a healthy gut and when to seek professional advice.”

The guide also aims to make the science feel less intimidating. Ellie Grove, Scientific Development Manager at SMA® Nutrition, said: “Parents are asking real questions about their baby’s tummy, from digestion to discomfort. In the first 1,000 days, our role is to translate topics like the gut microbiome and gut-brain connection into clear, useful information they can use day to day.”

How to improve gut health: easy ideas for weaning

To bring the guide’s advice to life in the kitchen, leading baby and children’s cookery author and feeding expert Annabel Karmel MBE has created gut-supporting recipes including Rainbow Veggie Orzo, make-at-home Baby Baked Beans, and a collection of first purées. They are designed to help parents introduce goodness-packed, fibre-rich foods from the very start of baby’s food journey.

“Weaning is an exciting opportunity to help shape a child’s lifelong relationship with food,” said Annabel Karmel MBE. “Introducing a wide variety of plant foods and flavours from the very beginning not only encourages adventurous eating but also helps support the development of a diverse, healthy gut microbiome. One of the best things parents can do is offer babies a colourful variety of fruits and vegetables, and my new gut-friendly recipes are a simple way to nourish little tummies.” 

SMA® Nutrition says the launch is designed to support families without adding pressure to their feeding journeys, bringing together expert guidance, simple explanations and practical support to help parents feel more informed as they navigate baby gut health, feeding and early development in the first 1,000 days.
