      The 7 wonders of breast milk

      Best for baby

      Learn what makes breastfeeding worthwhile

      Breast milk is incredible, multifaceted, and fascinating. It’s been inspiring our research for 40 years. And as we’re able to discover more and more about its composition, more unexpected and amazing properties are being revealed.

      7 wonderful facts that might surprise you:

      1

      Your breast milk is totally unique to you

      It's composition is determined by factors including your diet, hormones, genetics, environmental influences, and the needs of you and your baby.

      2

      Your baby recognises the smell of your breast milk1

      The scent of your breast milk prompts your newborn to show searching behaviours2. And, amazingly, they can sense and process information contained in your milk3.

      3

      Your breast milk can help your baby sleep

      As your hormone levels change throughout the day, so do the levels in your breast milk. This means, for example, that in the evening your milk will pass on sleep inducing hormones to your baby.

      Breastfeeding makes your ‘love hormones’ rise

      The skin-to-skin contact of breastfeeding is thought to help with bonding, but scientists have also discovered that your oxytocin levels go up while you breastfeed. This is thought to help increase your feelings of love towards your child5.

      Breast milk helps your baby have a healthier future

      Breast milk is filled with germ-fighting antibodies6. It can reduce the risk of developing eczema, asthma, allergies and obesity in later life7,8, while prolonged breastfeeding helps reduce the lifelong risk of heart disease9

      Breast milk can help your baby become a lifelong healthy eater

       Your diet can directly influence the composition of your breast milk10-13. And the foods you eat while breastfeeding could influence the tastes your baby enjoys throughout weaning and beyond14,15.

      Breast milk is different for sons and daughters

      Did you know that boys consume more of their mother’s milk than girls16,17? And amazingly, the breast milk produced for boys contains 25% more calories than for girls18,19.
