Fussy periods are normal for babies—here’s how to understand and manage them.
Caring for a fussy baby can be challenging and exhausting. Most parents find there are times when their baby is clingier, feeds more, and sleeps less.
These fussy periods are a normal part of your baby’s development and can occur at any age, sometimes lasting a few days or even weeks. While some babies have times when they appear to fuss and want to feed very frequently (known as cluster feeding), this article is about general fussiness that isn’t just about feeding patterns.
Why are some babies fussy?
It’s natural to wonder why your baby is unsettled. It was once thought that fussy periods were caused by growth spurts or appetite increases. Research shows that the amount of breastmilk a baby takes remains about the same from 1 to 6 months of age.1 Instead, these phases are likely linked to changes in your baby’s developing brain and temperament.
As your baby’s brain grows and they start to notice more about the world, they can become more sensitive and sometimes harder to settle. Every baby is unique—some are naturally more sensitive or reactive to their environment, which can make them more prone to fussiness. This is a normal part of development.2
During these times, your baby might be more unsettled, sleep less, and want to feed more often. Sometimes, this extra feeding is because your baby is genuinely hungry—young babies often need to feed more frequently than many people expect.
Other times, your baby may want to feed for comfort as they adjust to all the new things their brain is processing. Both reasons are normal, and responding to your baby’s cues with extra feeds and cuddles can help them feel secure during these stages.
Managing fussy times
Comforting your baby
Offer frequent feeds: Breastfeeding provides both nourishment and comfort through sucking and closeness.
Try a warm, deep bath: The soothing sensation can help calm your baby.
Gentle baby massage: Soft touch can be reassuring and relaxing.
Swaddling: Younger babies may feel more secure when wrapped.
Soothing sounds: Low music, singing, humming, or white noise can help settle your baby.
Gentle movement: Patting, rocking, swaying, or dancing can be comforting.
Wear your baby: Using a sling, wrap, or carrier keeps your baby close and secure.
Go for a walk: A change of scenery, even to another room, can help.
Reduce stimulation: If your baby is tired, use low lighting and minimize noise or distractions.
Caring for yourself
Try to eat and drink regularly: Keep snacks and water handy, and set reminders if that helps.
Rest when you can: Even short naps or quiet moments can make a difference.
Ask for support: Reach out to family or friends for practical help or emotional support.
Share the care: If possible, share baby care with another trusted person. If you’re alone and need a break, place your baby in a safe space for a few minutes.
Is it just fussiness?
Sometimes, fussiness is just a normal stage. But there may be other reasons for your baby’s behaviour. If they are more unsettled than usual, check if they might be unwell, like having an ear infection. Other causes can include nappy rash, teething, allergies or food intolerances, or separation anxiety—a normal part of development. If you’re worried, or your baby’s behaviour changes suddenly, talk to your healthcare provider.
