Newborn gassy and uncomfortable: why, and what to do
Pulling legs up, straining, fussing between feeds.
Updated May 2026
What's probably happening
A newborn digestive system is immature. Gas is the norm at this age, not a problem to fix.
In rough order of likelihood:
Normal newborn gut. Coordinating the reflexes to pass wind and pass stool is something the baby is still learning. Straining and red-faced effort are part of the work.
Air swallowed during crying or feeding. Crying makes them swallow more air, which makes them more uncomfortable, which makes them cry.
Mistaken for hunger. Rooting and crying overlap with the gas signal. They may not actually be hungry.
Foremilk-hindmilk imbalance (oversupply). Frothy or green stools, gulping at the breast, frequent fussiness — points to too much foremilk per feed.
When to escalate
If you need a break:
After 30 minutes with no progress, or any time frustration builds: put the baby on their back in the cot (crib). Step out for 5 minutes. Hand over to a partner if one is in the house.
Get immediate medical care:
Fever > 38°C in a baby under 3 months.
Crying nonstop for 2 hours despite the steps above.
Forceful or projectile vomiting — distinct from a small spit-up.
Blood or mucus in the stool.
