By Dr. Leo Bennett, Child Development Advisor | Expert Advice Column | Childcare Standards Council

In 2025, with growing public awareness about the role of nutrition in lifelong health, many parents are asking: What exactly should my child be eating to thrive? From fussy toddlers to busy school aged children, understanding your child’s nutritional needs can feel like navigating a minefield of advice, opinions, and marketing claims.

This article breaks down what we now know about childhood nutrition, offering balanced, science based guidance to support your child’s health, growth, and development without the confusion. Whether you’re preparing meals for a weaning baby or trying to encourage a picky eater, this guide is here to help.

Why Nutrition Matters So Much in Early Childhood

Childhood is a time of rapid physical, cognitive and emotional development. What children eat during these formative years directly affects:

• Brain development

• Immune function

• Bone growth

• Energy levels

• Behaviour and mood

• Long term health outcomes

  
  

Establishing healthy eating habits early on can also reduce the risk of obesity, type 2 diabetes, heart disease, and some cancers later in life.

Core Nutritional Needs for Children (Aged 1 to 5)

While nutritional requirements vary by age and individual needs, the following components form the foundation of a healthy childhood diet:

1. Macronutrients

• Carbohydrates: The body’s main source of energy. Choose complex carbs such as whole grains, oats, potatoes and brown rice.

• Protein: Essential for growth and tissue repair. Offer lean meats, fish, dairy, eggs, beans, lentils, and tofu.

• Fats: Vital for brain development, especially in the under fives. Prioritise healthy fats like avocado, olive oil, nuts (in paste form for under 5s), and oily fish.

  
  

2. Micronutrients

Children need a range of vitamins and minerals. Particularly important are:

• Iron: Prevents anaemia and supports cognitive development. Found in red meat, lentils, fortified cereals and leafy greens.

• Calcium: Crucial for bone and teeth development. Found in dairy, fortified plant milks, and green vegetables.

• Vitamin D: Helps absorb calcium and supports the immune system. Supplementation is advised for most UK children.

• Zinc, iodine, and B vitamins: Support growth, brain function and metabolism.

  
  

Updated Guidance on Vitamin D in 2025

Due to the UK’s limited sunlight for much of the year, NHS guidance continues to recommend vitamin D supplements for:

• All children under 5, regardless of diet or skin tone

• Babies who are breastfed (from birth)

• Formula fed babies who consume less than 500ml of fortified formula daily

  
  

In 2025, newer research continues to support the role of vitamin D in immune function and overall health, but there’s still no strong case for megadoses moderation and consistency remain key.

Weaning in 2025: Setting the Stage for Healthy Eating

Weaning typically begins around 6 months of age. Parents are encouraged to offer a wide variety of textures and flavours to encourage acceptance of healthy foods.

Current evidence based weaning strategies include:

• Offering iron rich foods early (like puréed meats, beans and fortified cereals)

• Introducing vegetables before sweet fruits

• Including common allergens (e.g. peanuts, eggs, dairy) in small amounts, one at a time, from 6 months onward

• Using a mix of spoon feeding and baby led approaches to encourage self feeding and autonomy

  
  

It’s also advised to avoid added salt and sugar in weaning foods and to steer clear of honey before 12 months due to the risk of botulism.

Managing Fussy Eating

Fussy eating is common particularly between 18 months and 3 years. While frustrating, it’s usually a normal developmental phase.

Evidence based tips for handling fussy eaters:

• Continue offering a wide range of healthy foods without pressure

• Eat together when possible, modelling positive food behaviour

• Serve new foods alongside familiar favourites

• Avoid using food as a reward or punishment

• Keep mealtimes calm and consistent

  
  

Research shows that repeated, low pressure exposure to a food can gradually increase a child’s acceptance it may take 10 to 15 attempts or more.

Hydration: Often Overlooked, Always Essential

Water should be the main drink for children after 12 months. While occasional milk or diluted juice is fine, sugary drinks and squash are best avoided to protect teeth and prevent excessive calorie intake.

Children can dehydrate more quickly than adults, especially during hot weather or illness. Encouraging regular sips of water throughout the day supports concentration, energy levels, and digestion.

Common Nutrition Myths in 2025

Despite increased access to information, many myths about childhood nutrition persist. Let’s address a few:

• “Children need supplements for everything.”Not necessarily. A balanced diet covers most needs; only vitamin D is widely recommended.

• “Natural sugars like honey or fruit juice are fine in large amounts.”Sugar is sugar. Whole fruits are best juices and syrups should be limited.

• “Organic food is always healthier.”Organic food avoids synthetic pesticides but isn’t necessarily more nutritious.

• “Children should clean their plates.”It’s better to teach children to recognise fullness than to eat everything served.

  
  

Supporting Healthy Habits at Home

In 2025, lifestyle continues to influence nutrition just as much as what's on the plate. Create a supportive food environment by:

• Involving children in food prep, even from a young age

• Offering regular meals and snacks at roughly the same times

• Eating together as a family, without screens

• Avoiding ultra processed foods when possible

  
  

These habits lay the groundwork for a healthy relationship with food and reduce mealtime stress.

When to Seek Help

While variations in appetite and eating patterns are normal, speak with a GP, health visitor or paediatric dietitian if you notice:

• Persistent refusal of entire food groups

• Weight loss or failure to gain weight

• Signs of nutritional deficiencies (e.g. fatigue, hair loss, pale skin)

• Difficulty swallowing or ongoing feeding aversion

  
  

Early support can help prevent more serious issues and set your child back on a healthy track.

Final Thoughts: Practical, Balanced Nutrition in 2025

Good nutrition in childhood isn’t about perfection it’s about balance, variety, and consistency. By focusing on whole foods, respecting your child’s cues, and following up to date evidence, you can feel confident you’re giving your child the nourishment they need to grow, learn and thrive.

And remember: it’s not about a single meal, but the overall pattern over weeks and months that truly matters.
