Perut babies memang boleh nampak besar dan "rounded" sampai berapa bulan, lah, terutama selepas minum susu, so that's usually normal! Tapi kalau baby nampak uncomfortable, banyak gas, atau perut keras terus, mungkin ada wind atau feeding issue yang boleh kita solve. A few of my mum friends had babies dengan perut yang nampak bloated, some kena adjust feeding position or pace, some just tunggu ja sampai digestive system mature. Kalau you worried or baby cranky/fussy pasal perut, better to check with the pediatrician just to be safe and get peace of mind lah, they can feel and assess properly.
