Hmm, 3 hari tak berak tu agak lama lah untuk baby 1 bulan, especially kalau dia dah biasa berak regularly, better check with your pediatrician just to be safe, sebab sometimes it could be constipation or feeding issues. The smelly gas boleh jadi normal, tapi combined with no poop 3 days, kena verify with doctor la to make sure semua okay je, a few mum friends kena face this situation and turned out okay after checking, but tak boleh assume je.
