Sayang, constipation dalam baby sebulan ni memang kena perhatian, especially since biasanya dia berak daily. Since dia still passing gas and urine, tu okaylah for now, tapi please see your paediatrician or go to the clinic today , jangan tunggu lagi sebab at one month old, important to rule out anything serious. A few of my mum friends pernah experience ni, and doctor diorang check sendiri, tengok if ada issues dengan feeding or digestion. Dia minum formula or breastfed? Sometimes positioning during feeding or gentle tummy massage boleh help, tapi doctor kena check dia dulu lah. Don't worry too much, biasanya okay ja, but better safe than sorry with newborns!
