@Charlotte did he have any other symptoms with this?
If no other symptoms it’s quite normal. I would try paced feeding if bottle and if breastfeeding maybe change positions and keep baby upright after feeds for 15ish minutes
@Yağmur we do pace feed as baby has suffered with reflux and she’s always kept upright for a good half an hour after her milk. We are not doing anything different but this has just suddenly started.
My baby had this issue and turns out he developed a milk allergy he’s now on dairy free formula and is ok
