Jarang kentut tu biasanya sign yang baby boleh tolerate formula baru tu better, jadi kurang gas lah, itu actually bagus! Tapi since you're seeing fewer burps + occasional constipation yang perlu massage baru keluar, mesti check dengan doc sebab sometimes ada babies yang memang perlu formula lain or adjustment, terutama kalau the poops jadi inconsistent macam tu (massive release then nothing for a day). A few of my mum friends noticed similar pattern bila tukar formula, but one of them found out later anak dia needs a gentler blend, so better confirm dengan paediatrician whether Dupro suits your baby's digestive system or perlu try lain. Dalam masa ni, the massage tu okay je maintain, tapi doc boleh advise lebih clearly whether tu normal adjustment period atau sign baby perlu switch.
