Hi There,
Some info for you from a reflux support website here in NZ.
About one third of all babies with reflux will have a cow's milk allergy or intolerance, and this can affect them through their mother's breast milk.
The foods that can make reflux pain worse for a baby/child are: Fruit and fruit juice, especially oranges, apples and bananas. Pears are the least acidic and an ideal first fruit for reflux babies.
Tomatoes and tomato sauce
Chocolate
Tea and coffee
Spicy Foods
Fizzy drinks (especially COKE)
Fatty foods (i.e. fish and chips!!)
NB:The above is for solid eating babies
It is important to note however, that these foods will not worsen vomiting, and so it is not necessary to avoid them in a 'happy chucker'.
Breastfeeding and the mother's diet
Citrus fruit, tomatoes, tea, coffee, Coke, alcohol and chocolate may also need to be avoided by the breast-feeding mother of a reflux baby. Some asthma medication (e.g. Theophylline) taken by the breast-feeding mother may also make the baby worse. Remember that all babies are different and different babies react to different foods - the list above is a guideline only.
Hope this helps
