What does letdown feel like when breastfeeding?
Some people notice tingling during letdown. Others feel nothing. Learn what the reflex is and which feeding signs may be useful to discuss with your care team.
The short answer
Let down is the reflex that squeezes milk toward the nipple when your baby sucks. It may feel like mild or strong tingling, but some people feel nothing. The NHS says a baby’s quick sucks can change to deeper rhythmic swallows as milk begins flowing.
What letdown means
During breastfeeding, your baby’s sucking causes muscles in your breasts to squeeze milk toward your nipples. This is called the letdown reflex.
The NHS says some people feel mild or strong tingling, while others feel nothing. Milk may also let down in response to your baby crying or when you have a warm bath or shower.
What you can notice during a feed
At the start of a feed, your baby may suck quickly to encourage milk to flow. As milk begins flowing, the NHS says these quick sucks can change to deeper, rhythmic swallows.
Sometimes a letdown is strong enough that a baby coughs or splutters. If this happens, the NHS recommends asking a midwife, health visitor or breastfeeding supporter for help.
When to get help
If you’re worried about breastfeeding or think your baby may not be getting enough milk, speak with a midwife or health visitor. They can help you review how feeds are going, including swallowing, nappies and weight gain.
The NHS also advises asking for help if pain doesn’t settle after your baby’s first few sucks, or if your baby falls asleep before the deeper swallowing stage. A midwife or health visitor can check positioning and attachment. This article summarizes United Kingdom guidance and can’t check your baby.
