Anak mama pun pernah macam tu dulu, especially after morning feed! Usually it's just milk di nose atau throat dia yang bikin bunyi, not necessarily congestion, normal je time tu pasal position menyusu. Tapi kalau bunyi tu persist atau ada signs lain macam demam, susah nak menyusu, or dia seems uncomfortable, better check dengan pediatrician just to be sure la, sebab kat 3 months lagi kena monitor closely. A few of us tried gently clearing baby's nose dengan saline nasal spray kalau nampak betul-betul ada hingus, tapi honestly kadang it goes away on its own. Jangan worry sangat lagi, but good idea to mention to doctor next visit so dia bisa check if baby's airway okay
