Is All This Baby Spit Up Normal

Welcoming a new baby into your life is an adventure filled with love, joy, and, yes, a bit of spit-up. Also known as reflux, spit-up is a common experience in newborns. While it might seem concerning at first, rest assured that spit-up can be typical in healthy infants, affecting more than half of all babies in the first three months of life.

Why do babies spit up? How can you help your baby with spit up? When is it normal spit-up and when could it indicate something else? Read on to learn more about reflux in babies. 

What Is Baby Spit-up?

Spit-up is when your baby’s stomach contents, including milk or formula, unexpectedly reappear during or after your baby’s feeding times. It usually involves just one or two mouthfuls and is often followed by a little burp. 

The good news? It typically doesn’t cause any discomfort to your baby and is often more concerning for parents than the baby. Your little one might even be a “happy spitter” and completely unbothered by the experience. 

Why Do Babies Spit Up?

Spit-up in babies can be influenced by several factors, including their feeding habits, the ongoing development of their digestive system, and their physical positioning. Here’s a breakdown of some of the common spit-up culprits:

Developing Digestive System

The lower esophageal sphincter, a muscular valve that prevents stomach contents from coming back up, is not yet fully developed in newborns. This can result in spit-up after feeding. It’s a natural part of growth, and as your baby grows, this valve will strengthen.

Lying Flat

Babies spend a lot of time on their backs, which can aggravate reflux. 


Spit-up can be triggered by trapped air in their tiny tummy. Some common reasons for gas build-up include swallowing air during feeding, crying, or using a pacifier.

Overstimulation Before or Right After Feeding

If your baby gets overly excited before feeding time, they might swallow too much milk or formula too quickly, which can cause gas and spit-up. 

Also, too much activity, like bouncing right after they eat, might upset their sensitive stomach.


Your baby’s belly is small. If your little one eats more than their tummy can comfortably hold, you might see some of that extra milk or formula return as spit-up.

How Much Spit-Up Is Normal?

Usually, babies spit up just a little at a time, about a spoonful or two. Sometimes, it might look like more when it’s spread out on their outfits, the crib sheets—or your shoulder.

Babies may spit up a few times a day, especially right after meals or during burp time. As they get bigger and their digestive system develops, you’ll likely notice less spit-up, typically by their first birthday. 

Tips for Managing Spit-Up

Here are some practical tips to help minimize spit-up and those little messes.

Feed in Smaller, More Frequent Portions: Overfeeding can overwhelm your baby’s tiny tummy. Offering smaller amounts more frequently can help reduce spit-up.

Keep Baby Upright: Holding your baby upright for 20 to 30 minutes after feeding can help keep their meal down. This position aids digestion and lets gravity do its work.

Burp Regularly: Burping your baby during and after feedings can release any trapped air in their stomach, reducing spit-up.

Check the Nipple Size: If you’re bottle-feeding, ensure the nipple size is appropriate for your baby’s age. Too fast a flow can cause them to ingest air and spit up more frequently.

Avoid Immediate Play: Give your baby’s stomach time to settle after feeding. Avoid bouncing or active play immediately after meals to reduce spit-up.

Limit the use of pacifiers. The continuous sucking of a pacifier can fill your baby’s stomach with swallowed air. 

Watch Your Baby’s Early Hunger Cues. Feed your baby as soon as you notice those first hunger cues, such as lip-smacking or sucking on hands or fingers. Once your baby becomes fussy and cries, they may gulp while eating, swallowing air and increasing the likelihood of spitting up. 

When Spit-Up Improves

Most babies start to spit up less around six months as they begin to sit up more independently and their digestive systems mature. The introduction of solid foods around this time also helps to keep stomach contents down. By 12 months, many children have outgrown the spit-up phase.

Distinguishing Spit-Up from Vomiting

It’s important to differentiate between spit-up and vomiting. Spit-up is generally effortless and doesn’t distress your baby, while vomiting is forceful and may indicate a health issue such as a virus, allergy, or blockage. If you’re ever in doubt, especially if your baby shows signs of discomfort, dehydration, or illness, it’s wise to consult your pediatrician.

When Should I Contact a Pediatrician About My Baby’s Spit Up? 

Spit-up is usually nothing to worry about, but there are a few indications that could suggest something else is going on:

  • If your baby isn’t gaining weight as expected, or if they’re losing weight
  • If your baby begins to spit up more than usual after they’re six months old, or if the spit-up is more forceful than before
  • Spit-up that’s bloody, yellow, or green in color
  • Excessive fussiness, irritability, and crying
  • Showing signs of discomfort or illness, like arching their back while spitting up 
  • Diarrhea or other digestive issues
  • Rash
  • Respiratory issues, such as wheezing or coughing

These issues could indicate that their spit-up is potentially related to a food allergy, sensitivity, GERD (gastroesophageal reflux disease), or another health matter. If your baby is experiencing the above or if for any reason you’re concerned about your little one’s spit-up, reach out to your pediatrician.

Embracing This Phase

Remember, while spit-up might be a bit messy, it’s a typical part of your baby’s development. With a little patience and some practical strategies, you’ll navigate this phase with ease. Always keep a burp cloth handy, maintain a sense of humor, and enjoy this special time with your baby. Their infant days will fly by, spit-up and all, leaving you with cherished memories of these precious early moments.
