Are there any foods I should avoid while breastfeeding
10 tips for breastfeeding success
A daily cup or two of coffee is fine, but too much caffeine can interfere with your baby's sleep or make him fussy. Remember that caffeine is also found in some sodas, teas, and over-the-counter medicines.
It's also okay to have an occasional alcoholic drink. But having more than one drink increases your blood alcohol level to the point that the alcohol gets into your milk. If you plan on having more than one drink at a time, wait two hours per drink before resuming nursing (or nurse, then have your glass of wine). There's no need to pump and dump unless your breasts are full and it's still not time to feed your baby. Moderate or heavy drinking is definitely not recommended while breastfeeding. An old wive's tale suggests that dark beer increases milk production, but recent studies suggest this is not true and that alcohol, in fact, reduces milk production.
If your baby has allergy symptoms (such as eczema, fussiness, congestion, or diarrhea), they may be caused by something he's in regular contact with, such as soap, mildew, or foods he's eating himself. Or he may be reacting to foods you eat that get into his system via your breast milk. It usually requires a bit of detective work to figure out exactly what's causing the sensitivity.
If you think that something you're eating is causing problems for your baby, it's usually something you've eaten two to six hours before feeding. The most common culprits include cows' milk products, followed by soy, wheat, egg, nuts, and corn or corn syrup.
Talk to your baby's doctor before you omit any foods from your diet. If avoiding a food could cause a nutritional imbalance (for example, if you eliminate all dairy products), you may need to see a nutritionist for advice on substituting other foods or taking nutritional supplements. Continue taking your prenatal vitamin as long as your baby's fully breastfed to cover any gaps in your own diet.
