Breastfeeding is the normal and natural way to feed and nurture a baby. If you have diabetes you may be concerned about whether you can breastfeed. The answer is yes.
All mothers experience metabolic and hormonal changes after giving birth. A mother with diabetes who breastfeeds has an advantage as breastfeeding reduces the impact of these changes. When you breastfeed, your body continues to support you and your baby, making your diabetes easier to manage in the days after birth. Later on, gradual weaning helps you to maintain control of your diabetes.

Adjusting your diet
It can be a shock if you are diagnosed with gestational diabetes during your pregnancy. This is usually a temporary condition in which your body fails to produce enough insulin to meet your extra needs while you are pregnant. It is usually diagnosed from the fourth month of pregnancy. Just like mothers who are on long-term treatment for diabetes, good control of blood glucose levels will minimise any problems for you and your baby. You may not need any extra medical care during labour and delivery. Diabetes treatment is usually unnecessary once you have given birth.
For you (as a diabetic mother)
- Breastfeeding increases your insulin sensitivity and has long term positive effects on your glucose metabolism.
• For Type-1 diabetes, breastfeeding will reduce the amount of insulin you need.
• For Type-2 diabetes, breastfeeding will reduce the severity of your diabetes.
• For Gestational diabetes, breastfeeding significantly reduces your risk of developing diabetes later in life.
- Breastfeeding suppresses your periods and monthly hormonal changes.
- See our page Amazing milk for more information.
For your baby
Studies show that your baby will be healthier throughout their life if they are breastfed. Infant formula increases a baby’s chance of developing diabetes.
Insulin treatment is compatible with breastfeeding. Insulin molecules are too large to pass into your milk. Check with your doctor for up-to-date information on any other medications you take. If there is any concern over safety, an LLL Leader can obtain information on named medications for you.
See Further reading at the end of the page for a selection of resources to help avoid these problems and overcome difficulties. You may also like to find out about your local hospital’s policies on the management of these and care of diabetic mothers during and after pregnancy.
Do ask if the hospital has an Infant Feeding Advisor who will be well informed about breastfeeding and a source of support in those early days.
This is the key to avoiding problems in pregnancy, labour and after birth. If you are planning a pregnancy, practise good diabetes management before you conceive too.
• Frequent antenatal and diabetes medical care will allow you to address any problems quickly.
• Discuss with the doctors, nurses and dieticians in your diabetes team how to control your changing needs for insulin, other medication and food while pregnant and after birth.
• You may be given a Continuous Glucose Monitor (CGM) which will notify you if your blood glucose levels get too high or too low.
• Monitor your blood glucose levels closely, so you can adjust your insulin, other medication and food intake.
You may need to eat frequent smaller meals a day to avoid hypos (hypoglycaemia or low blood glucose levels) and peaks in blood glucose levels.
Even with excellent control, diabetic mothers tend to have larger than average babies. Good blood glucose control will help limit how large your baby grows, making birth easier and reducing the risk of complications.
Your baby will be prone to hypoglycaemia (low blood glucose levels) during the first 12 hours after birth, particularly if you have poor blood glucose control in pregnancy. Even with good control, your baby will have been used to relatively high levels of glucose before he was born. The extra insulin he produces can lead to a drop in blood glucose after birth. Skin-to-skin contact, and early frequent breastfeeding will help avoid problems.
Check your hospital’s policy for testing blood glucose levels and treating a baby’s hypo. Your colostrum (first milk) is the best food for your baby if he has a hypo. If your baby has not breastfed yet, stored colostrum can be given.
In the last few weeks of pregnancy you can express some colostrum (early milk). This can be given to your baby if he can’t breastfeed after birth, or he needs supplements for any reason eg hypoglycaemia. Our information sheet Antenatal Expression of Colostrum explains how to do this before birth so you have some of your milk immediately available for your baby should he need any supplement.
The first few days
For many mothers with diabetes, milk production increases later than for mothers who don’t have diabetes. You can help your milk production increase normally on the third or fourth day with good control of blood glucose. Fluctuations in insulin levels will affect milk production, and increase the risk of your baby needing supplements. Get skilled breastfeeding help sooner rather than later to reduce the need for supplements. Your baby will need to stay in hospital for at least 24 hours after birth, until he is feeding well and maintaining blood glucose levels.
• Hold your baby against your skin after birth so he can breastfeed as soon as possible, ideally within the first hour after birth.
• Keep your baby with you unless separation is medically necessary.
• Try to breastfeed every hour for the first several hours, until your baby’s blood glucose levels stabilise. Ensure your baby feeds at least 8-12 times each 24 hour period.
• Spend as much time as you can holding your baby and encouraging him to feed frequently.
Separation and supplements
Take action if you and your baby are separated or if your baby needs supplements for any reason.
• Hand express small amounts of colostrum frequently to give to your baby. This will also help you establish milk production.
• Once you can express larger amounts, you can use a hospital-grade pump.
• Your baby can be given your milk with a syringe, cup or spoon.
Being separated from your new baby will be hard for you. As soon as you can, spend as much time as possible with him to help make up for lost time. Even visiting him in the neonatal intensive care (NICU) or special care baby unit (SCBU) will help, as you will be able to touch, stroke and talk to him and take over some of his care. You can ask to give him kangaroo mother care, in which a baby is snuggled skin-to-skin against mum’s chest. Kangaroo care helps to stabilise a baby’s heartbeat, temperature and breathing, and encourages breastfeeding. The hormones produced will help you express your milk, even if you can’t breastfeed straight away.
At first your blood glucose levels can change rapidly and you are at increased risk of having a hypo. Take suitable snacks into hospital so you have something readily available —and watch out for early signs of hypos.
Later you’ll have to manage your own health while caring for your baby. Keep suitable snacks and drinks within arms reach in all the places you are likely to breastfeed your baby to treat hypos at the first signs.
Seek skilled help straight away if you experience sore nipples or breasts, to reduce the risk of an infection. You are more at risk from a thrush infection of the nipple area if you have diabetes.
Rest when you can
Lack of sleep can make it harder to manage your diabetes and be a cause of stress, which means youor blood glucose levels will run higher. Try to rest when your baby sleeps and accept offers of practical help from others when you need to.
Breastfeeding helps your body adjust gradually to the metabolic and hormonal changes all mothers experience after birth.
You may need to eat many more extra calories a day while breastfeeding, eating regularly to maintain blood sugar levels. This will allow you to use your fat stores without the risk of ketones in your blood and urine.
Your local LLL Leader and Group can be a source of information and support. You may also find it helpful to meet with other mothers at your local LLL group. You will be able to share practical tips on breastfeeding and mothering and find out what is normal for a breastfed baby.
