Signs of a Baby Growth Spurt

Signs of a Baby Growth SpurtWhen your baby’s behavior seems out of the ordinary, you may wonder if she’s getting sick, teething or needs a schedule change. If none of the usual check list applies, your little one may be going through a baby growth spurt. You may not notice the growth at first, but when signs of a baby growth spurt are paired with sudden weight gain or sizing out of clothes, that’s probably what’s happening.

Although babies don’t all follow the same growth schedule, typically growth spurts occur around the same time for most babies. These include: 7-10 days, 2-3 weeks, 4-6 weeks, 3 months, 4 months, 6 months and 9 months. You may noticed that baby clothing sizes start to sync up with these traditional growth spurts, as do your baby’s check-ups. Growth spurts may last just a couple of days or up to a week.

If you suspect your baby is growing, keep an eye out for the most common sigs of a baby growth spurt:

Extreme Hunger

If your baby wants to nurse around the clock, a growth spurt is the likely culprit. As you can imagine, growing takes a lot of energy so your baby needs extra food to fuel her mission. Breast milk is the best nutrition for a growing baby because it contains everything her body needs to power growth and development. Don’t worry that your milk supply won’t be enough for her – your body will adjust to keep up with your baby’s nutritional needs.


Growth hormones are secreted during sleep so your baby may hunker down for some deep sleeping sessions during a baby growth spurt. Unless your pediatrician recommends otherwise, don’t wake your baby for feedings during a growth spurt. She’ll make up for the lack of milk during her natural waking hours. Also, be careful not to be too rigid with your schedule during a growth spurt. If your baby needs more sleep, don’t keep her up just because her normal schedule dictates it.


Your baby may be crankier than usual during a baby growth spurt. This may be because she’s hungry or tired or perhaps she’s tired because she was up eating all night. It’s hard to know for sure what is causing the fussiness during a growth spurt but do your best to meet your baby’s needs and keep her comfortable. Luckily it won’t last long!

If you’re unsure that your little one is going through a baby growth spurt, her signs are combined with other symptoms such as a fever, or she doesn’t come out of it within a week, consult your pediatrician as it may be something other than a growth spurt. Remember, growth spurts are a normal part of infancy and childhood. Your baby will be having them all the way through her teenage years.
