How to Tell If Your Baby Is Going Through a Growth Spurt

Ever wondered how to recognize a growth spurt in your baby? These spurts usually last a few days and can bring noticeable changes, here’s what to watch for: (2)(3)

1. Hungrier Than Usual
   • Your baby may suddenly want to feed more often—sometimes every hour or even every 30 minutes. If they’re demanding more milk or food without any clear reason, it could be a sign of a growth spurt.

2. Sleep Disruptions
   • Many parents notice their baby waking up more frequently at night. A baby who previously slept six straight hours might start waking every 1-2 hours. However, some babies do the opposite and sleep longer and deeper during a growth spurt.

3. Extra Fussiness
   • Even when fed, well-rested, and changed, your baby may still seem unusually fussy or unsettled. This can be frustrating for parents, but it’s just a temporary phase.

4. Changes in Behavior
   • Your baby might become more clingy, sometimes more emotional, or even pick up a new skill—like rolling over or crawling for the first time.

How to Handle Your Baby’s Growth Spurts?

As mentioned earlier, growth spurts can be a challenging time for parents, here are some tips to help you navigate this phase smoothly: (4)

1. Feed Your Baby as Often as Needed
   • Whether you’re breastfeeding, using formula, or introducing solid foods, it’s completely normal for your baby to want more frequent feedings. Follow their hunger cues and increase the number of meals as needed.

2. Help Your Baby Sleep Better
   • Be patient with your baby’s sleep disruptions. Offer comfort and reassurance to help them settle while trying to maintain their usual sleep routine as much as possible.

3. Give Extra Love and Comfort
   • Offer more cuddles and physical closeness. If your baby is fussy, try soothing techniques like skin-to-skin contact, a warm bath, gentle rocking, singing, or any other calming activity that brings them comfort and joy.

When Should You See a Pediatrician?

Growth spurts are a natural part of your baby’s development and usually last no more than a week. However, if your baby remains unusually fussy, unsettled, or difficult to soothe for more than seven days, it’s best to consult a pediatrician. (1)
