When breastfeeding, you should avoid or limit alcohol, caffeine, and high-mercury fish, while also being mindful of potential baby sensitivities to foods like dairy, soy, wheat, eggs, nuts, spicy foods, or gassy vegetables (broccoli, cabbage), and certain herbs (parsley, peppermint). The safest approach is a balanced diet, but if your baby shows signs of fussiness or allergy (rash, excessive gas, poor stool), consult a doctor or dietitian to identify triggers, which often include common allergens.
While breastfeeding, avoid or limit alcohol, caffeine, and high-mercury fish; you only need to cut common allergens (dairy, soy, eggs, nuts, wheat, fish, citrus) if your baby shows signs of sensitivity like fussiness, gas, or rash, as these can pass through breast milk, but consult a doctor before eliminating entire food groups for a balanced diet.
The "5-5-5 Rule" for breastfeeding is a simple guideline for storing expressed milk: 5 hours at room temperature, 5 days in the refrigerator, and 5 months in a freezer, though variations like 4-4-4 or 6-6-6 exist, with stricter rules (4-4-4) often recommended for warmer conditions, emphasizing getting milk into the fridge quickly. There's also a postpartum 5-5-5 rule for rest, suggesting 5 days in bed, 5 days near the bed, and 5 days near home to aid healing.
Five Foods to Avoid While Breastfeeding
If you notice that each time you eat something your baby becomes gassy or fussy, try avoiding the food for a while and see what happens. Many mothers have reported foods such as kale, spinach, beans, onions, garlic, peppers or spicy foods cause infant gas, while many babies tolerate these foods just fine.
The "4-4-4 rule" for breast milk is a simple storage guideline: fresh milk is good for 4 hours at room temperature (up to 77°F/25°C), for 4 days in the refrigerator (39°F/4°C or colder), and up to 4-6 months (or longer) in a standard freezer (0°F/-18°C). It's a handy mnemonic, though some organizations like the CDC recommend up to 6 months in the freezer and the AAP up to 9 months, with deeper freezers offering even longer storage.
Here are some common foods that make breastfeeding babies fussy:
The 30-30-30 pumping method is a power pumping technique to increase milk supply by mimicking cluster feeding: pump for 30 minutes, rest for 30 minutes, then pump for another 30 minutes, signaling your body to make more milk. This time-consuming, one-hour block aims to boost prolactin levels, with results often seen in 3-7 days, and is done once or twice daily as part of your regular schedule, replacing standard sessions.
When you are breastfeeding, you should avoid or try to limit smoking, most drugs, and alcohol. That will ensure the best health for you and your baby. If you have questions or concerns about smoking, drugs, or alcohol and breastfeeding, speak with your doctor or WIC breastfeeding staff.
When Is Breastfeeding the Hardest?
Common Breast Milk Storage Mistakes to Avoid
The "breast milk 2-hour rule" means any milk left in a bottle after a baby finishes feeding must be used within 2 hours or discarded, due to bacterial contamination from the baby's mouth, even if refrigerated, to prevent illness; it's best to offer smaller amounts to avoid waste. Unfinished milk can be saved if refrigerated immediately for the next feeding but must still be used within 2 hours of the initial feeding, never mixed with fresh milk, and thrown away if left at room temperature longer than 2 hours.
Garlic, onions, cabbage, turnips, broccoli, and beans. Apricots, rhubarb, prunes, melons, peaches, and other fresh fruits. Cow's milk. Caffeine.
The following snacks are quick and simple to make, and will give you energy: fresh fruit with a handful of unsalted nuts. lower-fat, lower-sugar yoghurts or fromage frais. hummus with bread or vegetable sticks.
Breast milk holds antibodies together with immune cells as well as protective proteins which improve maternal immunity to fight off infections. Here's how breastfeeding helps moms to get less sick: Antibodies: The protein substances called antibodies to fight bacteria and viruses in breast milk.
The hardest week with a newborn is often considered the first six weeks, especially weeks 2-3, due to extreme sleep deprivation, constant feeding demands, learning baby's cues, postpartum recovery, and a peak in inconsolable crying (the "witching hour"), making parents feel overwhelmed as they adjust to a new, exhausting routine. While the first week is tough, the challenges often intensify as the baby becomes more alert but still fussy, with major developmental hurdles like cluster feeding and increased fussiness peaking around 6-8 weeks.
But when your infant has painful gas, especially if it's frequent, it can cause your baby to cry or become fussy—until it's passed; unlike colic, which causes crying and fussiness that lasts for hours across days and weeks. Gas can have distinctive symptoms, too, such as a swollen-looking belly.
Green, bloody, or mucus-tinged stool—along with some other issues—could indicate a milk allergy.
Breastfeeding frequently—especially in the first hours, days, and weeks—is the main way to increase your milk supply. Your body will make milk to meet your baby's demand.
Pump at least 8 – 10 times in 24 hours until you are certain that you have more than enough milk for your baby. In the early months, you will need to pump at night, and most mothers find they cannot go longer than 4 hours between pumping sessions.
Studies suggest that, on average, a baby can consume between 2 to 3 ounces (60-90 ml) of milk from one breast in 10 minutes. However, this can vary widely among infants and mothers. Some babies may take in as little as 1 ounce (30 ml), while others can consume 4 or more ounces (120+ ml) in the same period.
Signs Your Breastfed Baby is Gassy
Include protein foods 2-3 times per day such as meat, poultry, fish, eggs, dairy, beans, nuts and seeds. Eat three servings of vegetables, including dark green and yellow vegetables per day. Eat two servings of fruit per day. Include whole grains such as whole wheat breads, pasta, cereal and oatmeal in your daily diet.
Signs your breast milk might be upsetting your baby include excessive fussiness, colic, green/mucousy/bloody stools, skin rashes (eczema/hives), reflux, poor weight gain, and respiratory issues like wheezing, often pointing to a sensitivity to something in the mother's diet, most commonly cow's milk protein. Symptoms usually appear shortly after feeding and improve within days of removing the trigger food, but severe signs like breathing difficulty warrant immediate medical attention.
