How Fasting Affects Breastfeeding...or does it? Happy Ramadan!
Spoiler alert...it doesn't! There are a few safety rules, but generally speaking it is not known to have a negative impact on a healthy mom or baby, milk supply or composition. You can fast while breastfeeding, but you may also find alternative solutions or choose to abstain this year.

Breastfeeding is highly regarded in Islam. The Qur'an regards it as a sign of love between the mother and child. In Islamic law, breastfeeding creates ties of milk kinship.
Allah states in the Qur’an, “Mothers shall give such to their children for two whole years, for those who wish the suckling to be completed…if after consultation, they choose by mutual agreement to wean the child, it is no offence for them…” (Al-Baqarah: 233).
During the month of Ramadan, Islamic religion involves fasting from sunrise until sunset. Also, according to Islamic Law, breastfeeding mothers do not necessarily have to fast. Breastfeeding mothers can also make up any missed fasts at a later date. If you choose to fast while breastfeeding that is also OK. Keep reading below to learn more about breastfeeding during Ramadan.
Muslims scholars and imams known as “Ulama", have been discussing breastfeeding while fasting for decades and still going. Ramadan is the most holy month of the year for Muslims. During the month, those who follow Ramadan abstain from eating, drinking, and sexual intercourse between sunrise and sunset. Also included in this is the practice of being extra patient, kind, and generous throughout a period of four weeks. Ramadan is right around the corner, this year it takes place from the Evening of Wed, Mar 22, 2023 - Evening of Fri, Apr 21, 2023.

Cultural & Religious Beliefs on Breastfeeding
Breastfeeding is important for different reasons to many people. Many Muslims view breastfeeding as the God (Allah) given right of the child according to Islamic law, as it is mentioned in the Qur'an/Koran, the holy book of Islam. If you follow the teachings of the Quran, you might strive to breastfeed your baby until the age of two years. However, it is not mandatory to breastfeed a child for two years if both the parents agree to wean the baby for a legitimate reason.
1. "Mothers shall breastfeed their children for two whole years, and for those who wish to complete the term" (2:233).
2. "His mother carried him, in weakness upon weakness, and his period of weaning is two years" (31:14). In a similar verse, Allah says: "His mother carried him with hardship, and gave birth to him in hardship. And the carrying of the child to his weaning is a period of thirty months" (46:15).
In some cultures extended breastfeeding is frowned upon. For example, in the sub-Indian cultures it may be acceptable for a girl to be nursed for longer, but not for a boy.
Many women around the world from various religions -- Muslims, Jews, Christians and Hindus -- choose to fast as fasting has not shown significant decrease in milk production if the hours are short, for example, between 5am and 7pm.
Should I fast while breastfeeding?
The decision is between you and Allah (God). An important factor to consider when you are thinking of fasting is the age of your baby. If your baby is still very young, less than 6 months old and therefore is solely dependent upon breast milk, then you should not fast.
If your baby is more than a year old, already on complementary foods and drinks breast milk only a few times a day, or only during bedtime, then you may be able to fast with little or no discomfort.
Fasting is not recommended while a baby is being exclusively breastfed.
How can fasting affect my breast milk?
Intermittent fasting is not thought to be associated with decreasing milk supply or a change in the major nutrient composition (fat, carbohydrate, protein) of breast milk. However intermittent fasting may affect the micronutrients (vitamins and minerals) in breast milk, such as zinc, magnesium and potassium.
Your body adapts to the changes in your diet by more efficiently using your calories and maintaining breast milk production. Research on breastfeeding mothers who had fasted shows that though there were very little changes in the amount of breast milk produced, it did change a little in composition.
The fat content of breast milk will remain unchanged during fasting. This is because your body will use your own fat deposits if you are not eating enough. Your baby's weight and growth rate will most likely remain unchanged if you are breastfeeding during Ramadan.
How do I know baby is getting enough?
Watch for these signs:
Weight gain 4-7oz a week / 0.5 - 1oz per day
Good diaper output; 5-6 wet or more and 1+ poo diaper per day
If you are worried your baby is not getting enough, signs of concern would be baby crying constantly, fewer wet diapers, weight loss, green stools, you should break fast and immediately contact your doctor and lactation consultant for a plan of care.
Missing Fast & Partial Fasting
Yes, missed fasts can be made up at a later date, but some breastfeeding mothers may prefer to fast with the rest of the family rather than fasting at a later date. If this is the case, and the baby is exclusively breastfed, it is recommend to discuss fasting with your primary care provider first to avoid complications. If you still want to fast, speak to your doctor about partial fasting for 2-3 days a week
Islamic and Cultural Practices in Breastfeeding
[…pregnant and breastfeeding mothers are exempt from fasting according to the Hadith--sayings of the Prophet].
Some mothers with children spaced very close together will choose to make up the fast after all of their children have weaned. Some scholars say that instead of making up the fasts, these mothers can pay a compensation by feeding poor people a meal for the number of fasts missed.
You should not fast if you:
have a baby less than six months old
live in extreme hot climate
tandem nursing
have multiples e.g. twins
at risk of severe dehydration
confirmed low milk supply
are supplementing
have a child that is underweight (preemies), ill, or takes medications or has a health condition that makes it difficult to breastfeed
