4-month-old vomiting a lot?
⚡ Short answer: If a 4-month-old is projectile vomiting or has bloody/greenish vomit, weight loss, or sluggishness, see a pediatrician the same day; otherwise, small amounts of spit-up right after feeding are usually normal reflux.

4-month-old vomiting a lot? My mother-in-law says one thing, I read something else.

It's completely understandable to be confused about vomiting — hearing different things from family and online is really frustrating.
First, here's an important distinction: Projectile vomiting (shooting out with force) is rare at 4 months and always needs a doctor's visit — this could be pyloric stenosis. But small amounts that drip from the mouth after feeding in a 4-month-old is very common. This is called reflux (GER); babies' stomach valves aren't fully mature yet, so it happens often. If your baby is gaining weight and seems fine, there's usually no problem.
When to take it seriously:
- Vomits large amounts after every feeding (nearly everything they ate comes back up)
- Vomits forcefully like a projectile
- Vomit is bloody, greenish (bile), or looks like coffee grounds
- Not gaining weight or losing weight
- Seems sluggish, unresponsive after vomiting
- Fever (38°C or higher, call 112)
When not to worry:
- Happening and gaining well
At home:
- Keep baby upright 20–30 minutes after feeding (on your shoulder, bouncer)
- Feed smaller amounts, more often
- Burp well (pause every 30–50 ml)
- Semi-upright during bottle-feeding, not flat
Real talk: 4 months is when reflux is most noticeable. If your baby's weight is good, wet diaper count is normal, and they seem content, time usually fixes it. But one pediatrician visit will put your mind at ease — and then you can tell your mother-in-law "the doctor said it's normal."
How is your baby's weight gain? Did the last checkup show any concerns?
