  • Fewer than 6 wet diapers per day
  • Weight loss or slowed weight gain
  • Constant crying after feeds
  • Lethargy or weakness
  • Baby feeds less often or doesn’t show hunger cues

You may need temporary formula supplementation — but only if there’s a true nutritional concern.

Remember: it’s temporary

A lactation crisis isn’t the end of breastfeeding — it’s a sign your baby needs more milk, and your body can meet that demand. Calm, rest, and closeness with your baby are your best allies.

Frequently asked questions about low milk supply

When does a lactation crisis usually occur?

Yes, a lactation crisis most commonly occurs at specific stages of infant development. It is typically seen around 3 weeks, 6 weeks, and 3 months of age, when feeding demand increases due to growth spurts. This is a temporary adjustment period and usually resolves within 2–4 days with frequent breastfeeding and continued night feeds.

Why does it feel like milk supply has decreased?

Often it does not reflect an actual decrease in milk supply. The baby may demand more frequent feeds, while the breasts feel softer and less full. This is a normal physiological adjustment where milk production adapts to the baby's changing needs, and perceived changes do not necessarily indicate low supply.

What should I do if I have low milk supply?

Continue frequent, responsive breastfeeding without restricting feeding sessions. Offer the breast on demand, including night feeds, as they support prolactin levels. Skin-to-skin contact, rest, hydration, and proper nutrition also help. With consistent stimulation, milk supply usually restores within a short period.

When should I see a doctor?

Seek medical advice if there are signs that the baby is not getting enough milk. These include fewer than 6 wet diapers per day, poor weight gain, excessive sleepiness, or persistent crying after feeds. A healthcare professional should assess feeding effectiveness and infant well-being to determine if intervention is needed.
