Small spit-ups remain completely normal, and simple reflux peaks around this age in babies who are otherwise gaining well. Forceful projectile vomiting, and any green or bloody vomit, are a different matter entirely. This guide separates the harmless from the urgent, and answers the upright-sleeping and special-formula questions honestly.
Pick the worry that fits your baby and open it for a clear answer, with what is usually normal, when to see a doctor, and when to go straight to hospital.
Small effortless spit-ups are common because the valve at the top of the stomach is immature. Normal reflux does not usually affect feeding, breathing, comfort, urine output or weight gain.
Small effortless milk spit-ups during or after feeds are common if the baby is comfortable, feeds well, passes urine and gains weight. Milk may also come through the nose without causing harm if breathing remains normal.
Vomiting or regurgitation is frequent and worsening, painful, associated with arching, coughing or choking, feeding refusal, reduced urine, poor weight gain, blood in stool, eczema, or the parent is unsure whether it is vomiting.
Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Feed responsively without overfeeding, check latch, burp gently and hold upright for about 20–30 minutes while awake. Protect clothing rather than repeatedly changing formula.
⭐ Zango Clinic’s view: At 15–28 days, a comfortable growing baby who spits small amounts is usually a happy spitter; warning signs matter more than volume guessed from clothing.
Spit-up is usually a small effortless dribble or flow. Vomiting is more forceful, repeated or associated with retching, distress or illness. Parents often overestimate volume once milk spreads over cloth.
Small effortless milk spit-ups during or after feeds are common if the baby is comfortable, feeds well, passes urine and gains weight. Milk may also come through the nose without causing harm if breathing remains normal.
Vomiting or regurgitation is frequent and worsening, painful, associated with arching, coughing or choking, feeding refusal, reduced urine, poor weight gain, blood in stool, eczema, or the parent is unsure whether it is vomiting.
Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Note colour, force, frequency, timing and the baby’s behaviour; a short video can help the clinician. Seek assessment if it is forceful or increasing.
⭐ Zango Clinic’s view: At 15–28 days, the distinction depends on force and the baby’s condition, not just how large the wet patch appears.
Progressively forceful or projectile vomiting between 2 and 8 weeks can be a sign of pyloric stenosis or another obstruction, particularly if the baby remains hungry, loses weight or urinates less.
Small effortless milk spit-ups during or after feeds are common if the baby is comfortable, feeds well, passes urine and gains weight. Milk may also come through the nose without causing harm if breathing remains normal.
Vomiting or regurgitation is frequent and worsening, painful, associated with arching, coughing or choking, feeding refusal, reduced urine, poor weight gain, blood in stool, eczema, or the parent is unsure whether it is vomiting.
Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Stop trying home remedies and arrange same-day urgent hospital assessment. Note the colour and number of episodes and bring feeding and weight records.
⭐ Zango Clinic’s view: At 15–28 days, repeated projectile vomiting is a surgical red flag until assessed and should not be labelled simple reflux.
Green or yellow-green bile-stained vomit may indicate intestinal obstruction; blood may come from gastrointestinal bleeding or swallowed maternal blood but still requires assessment. Neither should be watched at home.
Small effortless milk spit-ups during or after feeds are common if the baby is comfortable, feeds well, passes urine and gains weight. Milk may also come through the nose without causing harm if breathing remains normal.
Vomiting or regurgitation is frequent and worsening, painful, associated with arching, coughing or choking, feeding refusal, reduced urine, poor weight gain, blood in stool, eczema, or the parent is unsure whether it is vomiting.
Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Go to hospital urgently, especially with abdominal swelling, pain, lethargy or poor feeding. Do not give oral remedies or delay for another episode.
⭐ Zango Clinic’s view: At 15–28 days, green vomit is an emergency sign and bloody vomit requires prompt medical evaluation even if the baby initially looks settled.
Arching and crying may accompany reflux, but also occur with fast flow, swallowed air, overfeeding, poor latch, cow’s-milk protein allergy or normal crying. Reflux disease is considered when feeding, comfort or growth is affected.

Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Have a feed observed, avoid overfeeding, hold upright while awake and track weight. Discuss eczema, blood in stool or family allergy history before changing formula or maternal diet.
⭐ Zango Clinic’s view: At 15–28 days, arching alone does not prove acid disease; feeding assessment and growth should come before medication.
No. Even babies with reflux should sleep flat on the back on a firm surface. Inclined cots, side sleeping, pillows, wedges, car seats and swings are not safe routine sleep positions.

Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Hold upright only while awake after feeds, then place the baby flat on the back in an empty cot. Move a sleeping baby out of a car seat or swing as soon as practical.
⭐ Zango Clinic’s view: At 15–28 days, reflux care must not replace safe-sleep rules; back sleeping remains safest.
Most uncomplicated infant reflux needs reassurance and feeding adjustment, not acid-suppressing medicine. Thickeners, special formula or medicines have specific indications and can introduce risks if used without assessment.

Vomit is green or yellow-green, bloody, repeatedly forceful/projectile, or occurs with a swollen abdomen, severe pain, fever, breathing difficulty, marked sleepiness, dehydration or no urine.
✅ What you can do: Review feeding amount, latch and weight first. Use a thickener, formula change or medicine only under clinician guidance; never add cereal to a newborn bottle yourself.
⭐ Zango Clinic’s view: At 15–28 days, treatment should target documented feeding or growth problems, not normal spit-up; routine acid medicine is rarely the first step.
