Eh, perut kerap tu normal je lah, especially kalau dia aktif atau baru makan! A few of my mum friends pun pernah worried pasal benda yang sama, tapi paediatrician cakap long as dia sihat, happy, dan poop normal, tak perlu risau sangat. Tapi kalau kerap sangat sampai like every few minutes, or dia nampak uncomfortable, sakit, or ada other signs yang tak normal, better check with your doctor just to be sure, ok?
