Breast Milk

Breast Milk in a bottle and breast bump

Breast milk is the perfect food for babies, and can be used alone up to three months of age. It is cheap, easily digested, results in minimal faeces production, protects against numerous infections (eg. gastroenteritis, bronchiolitis) and is conveniently packaged for immediate use without any messy preparation.

Colostrum is the type of milk produced from one to five days after the birth of a baby, transition milk from five to ten days after birth and mature milk after that.

Breast milk can be scientifically analysed to detect the reason for infant feeding problems, a failure of the infant to thrive and inadequate or inappropriate milk production. The normal results are summarised below:-
