Abstract
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effects of dietary avoidance of cow's milk protein on the development of early wheezing or later asthma in infants at high risk of developing atopy. More specifically, we wish to quantify the risk of asthma and wheezing in infants fed standard cow's milk based formula, compared to infants in whom standard cow's milk was replaced with either soya‐based or extensively or partially hydrolysed milk formulae.
