Breast or formula milk provides the main source of protein for your baby's first seven to eight months. From this time you should be offering your child two portions of protein foods daily, such as pulses, lentils, beans, chickpeas, yoghurt or fromage frais. The protein in vegetable proteins may not contain all the amino acids your baby needs, but if you give a mixture of vegetable proteins together, all the necessary amino acids will be supplied. For example, for babies, puréed lentils with rice cereal, puréed broad beans with wheat based cereal; for toddlers hummus with rice cakes or peanut butter with bread. These combinations of foods would provide the full range of amino acids.
