Is it really low supply?

If you’ve noticed changes in your baby’s behaviour or your breasts, here’s what might be going on.

Young babies feed very frequently, often 8 to 14 times or more in 24 hours. Some babies continue to do this even as they get older. Breastfeeding your baby as often as they want will help ensure they get the milk they need.
Many young babies have very frequent feeds closer together for a period of time, often in the late afternoon or evening. This is sometimes called ‘cluster feeding’.
Babies may be fussy at the breast or come on an off. Sometimes this is just a slow let-down, not a supply issue. Find ways to help your milk to flow.
Breastfeeding is soothing. Babies may want to feed for comfort, not just hunger.
As babies get older, feeds are often shorter because they become more efficient at the breast.
After the first few months, breastfed babies may gain weight more slowly, even if they’re getting enough milk.
If your baby won’t settle after a feed they may e uncomfortable, tired or just want to be held. A top-up breastfeed can help.
Signs of too much milk can look like low supply. For example a baby who is fussy or wants to feed. But other signs of oversupply include lots of wet and dirty nappies, and green, frothy or explosive poos.

Breast size doesn't affect how much milk you can make. Small breasts can make plenty of milk. Your baby may just need to feed a little more often.
After a few weeks, breasts often feel softer and less full. This Is normal.
If your breasts feel empty at the end of the day, that’s okay. When babies feed frequently and remove milk well, your breasts won’t feel big and full.
You don’t need to wait for your breasts to 'fill up'. The more your baby feeds, the more milk you make.
Not feeling your let-down reflex? Many mums don’t. Watch for your baby’s sucking patterns. A rhythmical suck-swallow pattern with regular swallowing means your let-down is working and your baby is getting milk.

Expressing is a skill that takes time to learn. The amount you can express isn’t the same as how much milk your breasts make. Most babies are better at removing milk than a pump.
If you express straight after a breastfeed you might not get much. Your breasts are never empty but your baby will have taken most of what’s there. Wait about half an hour and try again.
