Why is my newborn vomiting?
Newborn babies can vomit for all number of reasons. While it's distressing for parent and baby alike, there is usually a very simple explanation.
In the early days after the birth, many babies will vomit up mucous from their stomach. This is mostly the remnants of the amniotic fluid that was swallowed in the womb, mixed with mucous produced by the lining of the baby's stomach, in preparation for absorbing milk feeds.
Baby vomiting mucus
Occasionally, a baby's mucous can be quite thick, and the baby may temporarily gag on it in the back of their throat. This can cause them to look like they are choking, and possibly go red, or blue, in the face. Understandably, parents find this quite distressing to watch, however babies will usually deal with it on their own. Sitting your baby upright, or placing her over your shoulder, will generally help her to swallow the mucous or spit it out.

Baby vomiting after feeding
Once your baby is taking larger volumes of milk, it is very normal for her to vomit, or 'regurgitate', part of the milk around feed time. (However, some babies do not vomit much until they are about 2 to 3 months old.) Your baby may vomit a lot, or only on occasions. If you are lucky, she won't vomit at all, unless she is physically unwell. Most babies will tend to vomit 'off and on' at various stages during the first 12 months of their life. A few babies will have problems associated with vomiting, due to reflux.
Your baby may have little 'delicate' vomits that just overflow gently from their mouth, or they may vomit with dramatic style, in a great gush coming from the mouth and nose! (A very attractive party trick!) Observing this type of vomit can leave parents feeling very concerned (and possibly astonished, at the sheer force of it), or upset about all the milk that has 'gone to waste'. Unlike adults and older children, babies vomit quite effortlessly, and don't often seem disturbed, or distressed by it.
Common causes of baby vomiting
The most common cause of a baby vomiting in the early weeks is by some of the milk being brought up with a pocket of air, when your baby burps.
The other term for this type of vomiting is 'positing'. If milk comes up soon after a feed, it looks (and smells) fairly similar to how it went down - a milky liquid. If the milk comes up a while after the feed, it will usually be partially digested, and often have lumps of curdled milk. Partially digested breast milk doesn't tend to have a strong odour, but formula milk usually will.
The other reason why babies vomit frequently is because the muscle valve at the top of their stomach (between the oesophagus and the stomach) is weak and immature. In adults, this valve closes tightly after swallowing food, to keep food down. It takes a great deal of force to push this valve open to allow an adult to vomit. For babies, the valve does close, but not as tightly. It can be easily forced open with gentle pressure behind it.
In the normal process of digesting milk (and food), and then guiding the stomach contents into the bowel, the stomach performs a 'contracting' action. The pressure from these contractions can force milk back up the baby's oesophagus, to vomit. This may also happen if the baby's stomach is 'overfull', or is gently pressed on. For example, by resting the baby too far over your shoulder, or your baby is slouched over while sitting, or if she is having 'tummy time'.

Most babies who vomit frequently are happy, healthy and put on weight. They will eventually 'grow out' of it by the time they are one year old (or even earlier for some). It may improve somewhat, after six months or so, when your baby is eventually sitting up, and spending more time in upright positions, as gravity will often help to keep things down.
For many parents, it can be hard to keep a smile on your face, if you feel that you are constantly covered in vomit, or it is seeping down the back of your new lounge! Carrying around a spare cloth nappy or hand towel, often becomes part of your wardrobe.(Some parents buy coloured ones, to 'coordinate' with their outfits!)
If you are concerned that your baby is vomiting excessively, or seems unwell or distressed, you should seek medical advice. Vomiting in conjunction with any of the following symptoms could be a concern and require a visit to medical professional:
- having less than six wet nappies in 24 hours
- losing interest in feeding
- being lethargic
- having diarrhoea
- having a fever
- the vomit having a very offensive smell or if it consists of clear, bright yellow, orange or greenish bile fluid
Blood in baby vomit
In the first few days after the birth, it is not unusual for a baby to vomit up small amounts of old blood. This is because babies often swallow blood during the birth (whether a vaginal birth or Caesarean). The blood in the vomit usually looks dark red, or brown and 'coffee ground' in appearance. This will not harm your baby, and will slowly work its way through her system.
Blood can also be seen in a newborn's vomit if you have cracked and/or bleeding nipples (usually damaged from incorrect positioning of the baby on the breast). Occasionally, the skin of the nipples may not even look obviously split or broken, however there is some soreness associated with the baby suckling. The blood in the baby's vomit may give the milk a pink, or dark red stain, or look like streaks of dark brown. Again, the blood will not harm your baby but you may need to look at correcting your baby's attachment for breastfeeding, to prevent further nipple damage. Do not stop your baby from breastfeeding, just because she is swallowing blood.
If your baby is being formula fed and you notice blood in her vomit, or if the blood appears in the breast milk continuously and you don't think you have nipple soreness (or any signs of damaged nipples), you should seek advice from your local doctor.
How to cope with your vomiting baby
- Keep spare nappies, hand towels or washers handy during and after feeds. Carry one around with you when you go out and make use of bibs over gorgeous new outfits, until your baby is 'on show' for special occasions.
- Handle your baby gently after feeding. Avoid jiggling them around and lifting them up and down too quickly. (This can have the same effect as the 'Big Dipper' ride).
- Many parents worry about replacing what has been brought up. If your baby seems hungry, offer them the breast again, or give them another 40 - 60ml of formula (or whatever amount they are happy to take).
- DO NOT change your baby's feeding pattern in an attempt to fix the vomiting. Giving her more feeds, or spacing feeds further apart will not alter a baby's vomiting.
- DO NOT change your formula, if bottle feeding. This will not prevent your baby from vomiting.
- DO NOT thicken formula (or add other substances such as rice cereal) in the belief that it will be 'heavier' and therefore stay down. Altering directions for formula preparation can lead to constipation, unhealthy weight gains and possibly cause vomiting, making your baby unwell.
- Remember, the majority of babies who vomit thrive, and are not worried by it. Although their parents may be!
