Sayang, yang penting baby okay minum dan kencing normal macam you said, tapi 7 hari x berak tu memang boleh jadi a bit concerning. Please contact your pediatrician or go to the clinic soon okay, even if baby's tummy looks fine, sebab doktor perlu check properly. Constipation boleh jadi many reasons, especially dengan mixed feeding, so better to get professional advice untuk peace of mind you! Jangan delay tau.
