Any alcohol you drink passes to your baby through your breast milk, so be careful about your consumption of alcoholic beverages. The longer you breastfeed, the more you'll realize what you can and cannot eat and drink. A common breastfeeding problem for some women is breast engorgement. The breasts become swollen, tender and filled with breast milk. The best cure is to drain the breasts, if possible, as by breastfeeding.
Some women take a hot shower and empty their breasts in the warm water.
Ice packs may also help. Acetaminophen is recommended by the American Academy of Pediatrics as safe to use while you're breastfeeding. You might need to use stronger medications, such as Tylenol with Codeine, a prescription medication. Call your doctor if engorgement is especially painful. He or she will decide on treatment.
