Fasting While Breastfeeding: What You Really Need to Know
Ramadan is one of the most beautiful times of the year. The stillness before Suhoor. The warmth of Iftar with family. The sense of gratitude that fills the whole month. But if you are a nursing mum, you might be wondering — can I fast while breastfeeding? Will my susu ibu be affected? Is it even okay to skip puasa this year?
You are not alone in asking these questions. Many Malay-Muslim mothers in Singapore sit with this exact tension every Ramadan. This guide is here to help you feel informed, supported, and at peace — whatever you decide.
Is It Safe to Fast While Breastfeeding?
For most well-nourished mothers, short-term fasting during Ramadan does not significantly affect breast milk volume. Research suggests that milk composition stays relatively stable, though there can be small changes in fat and lactose levels when fasting is prolonged or if a mother becomes dehydrated.
The bigger concern in Singapore is our heat and humidity. Fasting through a 30-plus degree day is very different from fasting in a cooler climate. Dehydration is the real risk here, not caloric restriction alone. When you are dehydrated, your body prioritises its own needs — and your milk supply can dip as a result.
Mothers in the early postpartum period — especially those with newborns or babies under three months — face a higher risk of supply changes during fasting. If your baby is very young or you are exclusively breastfeeding, it is worth having a conversation with your doctor or a lactation consultant before Ramadan begins.
The WHO breastfeeding guidelines recommend exclusive breastfeeding for the first six months of life. Keeping your supply strong during this window matters — and with the right support, many mothers absolutely do.
What Does Islam Say About Fasting While Nursing?
This is such an important question, and the answer is genuinely reassuring. Most Islamic scholars agree that breastfeeding mothers are permitted to skip or delay their fasts if they fear harm to themselves or their baby. This exemption is called a rukhsah — a mercy granted by Allah — and it places nursing mothers in the same category as pregnant women and those who are unwell.
Skipping puasa to protect your baby and your milk is not weakness. It is not a failure of faith. It is a provision your religion has lovingly made for you. Fasts can be made up later (qada) when you are ready. Many scholars also note that fidyah may apply depending on your circumstances — your religious teacher or imam can guide you on what is appropriate for your situation.
Some mothers choose to fast anyway and feel absolutely fine. Others find it genuinely difficult. Both experiences are valid. The goal is to make the decision that is right for your body, your baby, and your faith — not to follow anyone else’s pressure or expectations.
Does Fasting Affect Milk Supply?
It can — but it does not have to. The key variables are hydration, nutrition, and how frequently you continue to nurse or express.
Your body is remarkably good at protecting your breast milk even when resources are limited. But when dehydration sets in, or when Suhoor is skipped in favour of a few extra minutes of sleep, or when Iftar turns into fried Ramadan bazaar food and sugary drinks, your supply can feel the strain.
The good news is that you have a window between Iftar and Suhoor to really nourish yourself. How you use that window makes a significant difference.
What to Eat at Suhoor to Support Breastfeeding
Suhoor is your most important meal during Ramadan when you are breastfeeding. Think of it as fuelling both yourself and your baby for the hours ahead.
Here is what to prioritise:
- Protein: Eggs, legumes, fish, and Greek yogurt help sustain your energy and support milk production throughout the day.
- Complex carbohydrates: Oats, wholemeal bread, and brown rice release energy slowly and keep you going longer.
- Healthy fats: Avocado, nuts, seeds, and coconut support milk fat content and help you feel fuller for longer.
- Galactagogue-rich foods: Oats, almonds, flaxseed, and dates are all traditional foods that are also nourishing for breastfeeding mothers.
- Water: Drink as much as you comfortably can at Suhoor. Even one or two extra glasses makes a difference.
If Suhoor feels rushed or you struggle to eat a full meal at dawn, having something convenient and nourishing on hand is a real lifesaver. Our SLB lactation bakes are halal-certified and made with oats, nuts, and other wholesome ingredients — exactly the kind of easy, nourishing option that fits into a quiet pre-dawn meal. A couple of lactation cookies or a muffin with a big glass of water is a genuinely good Suhoor in a pinch.
What to Eat at Iftar to Support Breastfeeding
Breaking fast with dates is a beautiful sunnah — and dates genuinely are a great choice for nursing mothers too. They provide quick energy and contain natural sugars, fibre, and minerals that are helpful after a long day.
After that first date and some water, try to build your Iftar plate with:
- A good source of protein — ayam masak merah, fish curry, lentil soup, or eggs.
- Vegetables and fibre to support digestion and overall nourishment.
- Whole grains where possible rather than white rice or white bread alone.
- Plenty of water and hydrating fluids — coconut water is a lovely option.
We know the Ramadan bazaar at Geylang Serai smells absolutely incredible. The occasional murtabak or kueh is a joy, not a crime. Just try not to let fried and sugary foods make up the bulk of your Iftar — your body and your baby will thank you.
A lactation brownie or muffin after Iftar is a lovely treat that also supports your breastfeeding journey. It feels indulgent but it is quietly doing good work at the same time.
Tips to Maintain Milk Supply During Ramadan
Beyond what you eat, here are some practical ways to protect your supply throughout the month:
- Keep nursing or expressing frequently. Supply works on demand. The more your baby feeds, the more your body is signalled to produce. Do not reduce nursing sessions during fasting hours.
- Rest when your baby rests. Fatigue is a real supply disruptor. The broken sleep of Ramadan nights adds up. Nap when you can.
- Hydrate aggressively between Iftar and Suhoor. Aim for eight to ten glasses of water across your non-fasting hours. Set reminders if you need to.
- Watch for signs your baby is getting enough. Consistent wet diapers and steady weight gain are your most reliable indicators.
- Be kind to yourself. Stress and guilt also affect supply. You are doing something hard and beautiful. Give yourself grace.

Signs Your Milk Supply May Be Dropping During Fasting
Watch for these signals during Ramadan:
- Fewer wet diapers than usual (less than six per day is worth noting)
- Baby seems unsettled, fussy, or wants to nurse constantly
- Baby is not gaining weight as expected
- Your breasts feel consistently empty or not as full as usual
- You feel very thirsty, dizzy, or lightheaded
- Dark-coloured urine — a sign you need more water
If you notice several of these signs together, take it seriously. Break your fast if you need to. Your baby’s needs and your health come first, and Islam has already given you permission to do exactly that.
When You Should Consider Not Fasting
There is no shame in choosing not to fast this Ramadan. The following situations are ones where most healthcare providers and scholars would counsel extra caution:
- Your baby is a newborn or under three months old
- You are exclusively breastfeeding and your supply is already low or fragile
- You have a history of low milk supply or supply issues
- You are unwell, anaemic, or recovering from a difficult birth
- You are experiencing significant dehydration or dizziness
If you are unsure, please speak to your doctor or reach out to our IBCLC-certified team. Getting personalised guidance is always better than guessing. KKH lactation consultants are also a trusted resource for Singapore mothers navigating exactly these questions.
The NHS breastfeeding advice also recommends that mothers who feel unwell or notice changes in their baby during any period of dietary restriction seek support promptly.
Frequently Asked Questions About Fasting While Breastfeeding
Can I fast while breastfeeding in Singapore?
Many mothers do, and many do so comfortably. It depends on your health, your baby’s age, and how well you can nourish and hydrate yourself during non-fasting hours. Singapore’s heat makes hydration extra important. Always listen to your body and consult your doctor if you are unsure.
Will puasa reduce my breast milk supply?
It can, especially if you become dehydrated. But with good nutrition at Suhoor and Iftar and frequent nursing, many mothers maintain their supply well throughout Ramadan.
Is it haram to skip fasting because I am breastfeeding?
No. Islamic scholars grant nursing mothers a rukhsah — a permitted exemption. You can make up your fasts later through qada. This is a mercy from Allah, not a failure of your faith.
Can I eat lactation cookies during Ramadan?
Yes, absolutely. SLB lactation cookies and bakes are halal-certified and work beautifully as a Suhoor or Iftar option. They are made with oats and other nourishing ingredients that support your breastfeeding journey during the limited eating window.
My baby seems hungrier during Ramadan. What should I do?
Increased hunger or fussiness can sometimes indicate a dip in supply. Check wet diapers and if you are concerned, increase your fluid intake and nurse more frequently. If things do not improve, seek support from a lactation consultant.
Does fasting change the taste of breast milk?
Some mothers notice their baby is slightly fussier during Ramadan. Extended fasting can produce mild ketones in the body, which may subtly alter milk taste. Most babies adjust. If your baby continues to refuse the breast, seek support.
A Gentle Reminder to Singapore Mamas This Ramadan
You are navigating something genuinely complex — your faith, your body, your baby, and the expectations of the people around you. That is a lot to carry.
Whatever you decide about fasting this Ramadan, know that caring for your baby and protecting your milk is an act of love and worship too. Feed yourself well during the hours you can. Rest when your baby rests. Nurse often and drink plenty of water. And reach for nourishing, halal-friendly support whenever you need it.
Ramadan Mubarak. You are doing beautifully.
