Baby Growth Spurts: How To Detect Them And What To Do

baby growth spurts

One of the most commonly discussed topics among parents is the phenomenon of growth spurts.  You’ve probably heard parents, relatives, and friends discuss baby growth spurts, haven’t you? But what is a growth spurt? Are they random occurrences? What impact do they have on your child’s long-term development? Here are some interesting and useful facts about growth spurts. 

What Are Baby Growth Spurts?

The stages of accelerated growth are termed growth spurts. During a growth spurt your baby will suddenly intensify their rate of growth in weight, length, and head circumference.   

What Are The Signs Of Growth Spurts?

Although they vary from one baby to another, the main evidence will be a change in your child’s behavior patterns, such as:

Appetite: Since we don’t typically weigh and measure children daily, the most noticeable sign of a growth spurt might be a sudden increase in appetite. To identify growth spurts, look out for times when your little one seems particularly hungry. If you are breastfeeding, it’s likely that you notice your baby lengthens time. On the other hand, if your baby is formula-fed, they are likely to feel hungry after finishing their bottle. 


Sleep: Apart from feeding more, changes in sleep periods may be another sign that your baby’s body is channeling their energy to grow. Just before or during a growth spurt your baby may seem sleepier than usual, wake up less at night or take more and longer naps. To be noted, a small proportion of babies may sleep less during growth spurts.  

Clinginess: During a growth spurt your baby could act more restless and clingy than usual. These changes in behavior may be due to your baby feeling tired as their energy is devoted to feeding and growing.

Babies experience major growth spurts during their first 12 months. There’s no rule as to when they occur, but experts have identified certain points when they commonly show up: 

  • 2-3 weeks
  • 4-6 weeks
  • 3 months
  • 6 months
  • 9 months

Tips To Manage Baby Growth Spurts:

  • Keep calm, growth spurts only last a few days.
  • Take into account that growth spurts are caused by a specific protein, the human growth hormone (HGH), which is produced in the brain while sleeping. HGH is vital for growth, so allowing baby to sleep extra hours is positive and necessary.
  • Finally, don’t worry if your baby doesn’t exhibit symptoms of growth spurts. Some babies go through several evident growth spurts, while others does not show any of the signs  mentioned here. It’s all normal.

Finally, there’s no hard evidence to prove that growth spurts bring about a faster cognitive, motor, or social development. But it is a fact that a baby’s brain and skull physically enlarges along with the rest of the body during growth spurts. So, smile! You might find that after a growth spurt, your little one has acquired a new ability or hit a new milestone, and that’s a positive end to a few days of extra care and feeding.
