Spit- ups are very common in babies And its not a thing to be worried about. Its absolutely normal. If your baby is content and gaining weight (s)he can be called Happy Spitter. spit ups are a normal part of infancy due to swallowed air with their feedings

But parents gets confuse between spit ups and vomiting. Spit ups are non-stressful, passive and often come up with a burp. They can be so silent as to not notice it even happened. The baby will not usually mind either. It is caused by weakness and immaturity of the valve between the stomach and esophagus and most resolve by 12 months.

Vomiting, on the other hand, is forceful ("retching") and involves larger amounts of feeding -- sometimes all of it. It can be quite distressing to the baby. Vomiting is abnormal but not necessarily an emergency. Common causes are stomach viruses and other infections (earache or upper respiratory), overfeeding and food allergies. The baby may run fever.

Babies take in a lot of nourishment in relation to their size, and some of them really like to eat, so sometimes they become overfilled and, well, overflow.

A newborn's digestive system isn't fully developed, either. The muscles at the bottom of your baby's esophagus, which control whether food is coming or going, may still be getting up to speed. It's no wonder your baby creates so much laundry.

Here are a few tips to help an infant who vomits:

• Avoid overfeeding. Smaller and frequent feedings will empty the stomach faster.
• Minimize intake of air during feeding. If the bottle is too low, the baby can swallow air, causing gas and crying.
• Don't jiggle the baby during and after feeding. Too much movement may cause reflux.
• Sit her in an upright position after feeding. Sitting and lying on the back makes reflux worse. Hold the baby in your arms as much as you can.
• Elevate the crib at a 30-degree angle. I suggest using a book under the legs at the head of the crib. Do not use pillows since this can cause suffocation.
• With your pediatrician's approval, put a baby with severe GERD to sleep on her tummy. The American Academy of Pediatrics recommends that babies sleep on their back in order to avoid SIDS. There is an exemption for babies with severe GERD since it can improve gastric emptying. Only follow this under doctor's orders.
• Avoid exposure to tobacco smoke. This relaxes the esophageal sphincter.
• Thicken formula with rice cereal. Add one tablespoon of rice cereal for every two ounces of formula and cross-cut the nipple to facilitate the flow of this mixture. Although this may improve reflux, it can cause excessive gas and constipation. Consult your doctor before trying.
• Burp your baby after each feeding. In fact, if your baby takes a natural pause during a feeding, take the opportunity to burp him before giving him more food. That way, if there's any air, it'll come up before even more food is layered on top of it. (Don't forget to put a soft cloth on your shoulder first!)
