Claire’s eight-week-old baby, Jamie, was apparently healthy but cried a lot of the time, and seemed to be in pain. As Claire was breastfeeding, her doctor asked about her diet and found that she was a vegetarian. She explained that she had been eating more cheese and drinking an extra pint of milk a day to make sure she got enough protein during pregnancy and breastfeeding. The doctor suggested that she might avoid milk, cheese and butter for a while, to see if this had any effect, and prescribed some tablets to give her extra calcium. He persuaded her to eat a little fish to make up for the missing protein. A couple of days after starting this diet, Jamie’s crying was noticeably less and it became easier to get him to sleep each evening. Claire was delighted at the improvement. She tried drinking a glass of milk, to see what would happen, and 24 hours later Jamie, following a feed, suffered, a severe attack of colic. After that, Claire stayed on a milk-free diet for six weeks. She then introduced a little milk and butter into her diet and found that Jamie could now tolerate this.
