Questions and answers
Where can I borrow a pump from?
Some centres offer short-term loans of hospital-grade breast pumps. There is usually a small charge for the pump parts, which you keep, while the pump itself is loaned to you. You can find details in the useful links section on this page. If you need to use a breast pump regularly, contact your local breastfeeding or infant feeding support service, or call our advice line for support.
Should I express my milk overnight?
Yes, you can. Expressing overnight can help if you are trying to increase your milk supply. Between 1am and 5am, levels of the hormone that supports milk production are at their highest, so expressing during this time may help your body make more milk.
How do I store my breast milk?
Store expressed breast milk in a clean, sterilised container or breast milk storage bag. Label it with the date it was expressed. Depending on when you plan to use it, breast milk can be stored at room temperature for a short time, kept in the fridge, or frozen. Before using stored milk, check its smell and appearance. If you want to warm it, place the container in warm water rather than using a microwave.

How do I offer my expressed breastmilk to my baby?
You can give your baby expressed breast milk using a cup, bottle, or a nursing supplementation system alongside breastfeeding, until they are able to feed effectively directly from your breast. It’s a good idea to ask for support when using these feeding methods, to help protect your breastfeeding journey and make sure things are going smoothly. You can speak with your Health Visitor, attend one of the breastfeeding support groups, or contact the advice line for extra help and reassurance.
Do I need to sterilise my breast pump after every use?
Wash all parts that come into contact with milk after every use. You should sterilise them at least once a day to help protect your baby from germs.
Can I get back to direct breastfeeding after expressing?
Yes, many babies can move back to feeding directly from the breast after a period of expressing. This can take time and patience. Your health visitor, infant feeding team or local breastfeeding group can offer advice and reassurance. If your baby is having top-up feeds alongside breastfeeding, they can help you decide when and how to reduce these safely.
Should I single express or double express?
If you have a pump that allows you to express from both breasts at the same time, double expressing may save time and help you express more milk. Single expressing can still be effective and may be a better option if you only have a single pump or find it more comfortable.
Can I hand express my milk?
Yes, hand expressing is a way of collecting breast milk without using a pump. Many parents find it convenient because all you need is clean hands and a container to collect the milk. It can be useful in the early days, if you are away from home, or if you only need to express a small amount. Some parents also find it easier to express more often using this method.
How do I know what size flange to use?
If you use a breast pump, the right flange size can help make expressing milk more comfortable and effective. A flange that does not fit properly can cause soreness and may affect milk flow. The flange included with your pump may not be the right size for you, so it is important to check the fit. A guide to measuring your nipple is available in the useful links section of this page. If you need help, speak to your health visitor or infant feeding team.
