Salam! Degupan jantung baby memang penting, tapi kecepatan normal bergantung pada banyak faktor, umur, aktiviti, suhu badan, semua influence. Sebab baby 1 bulan ni masih sangat muda, please see your paediatrician or go to clinic/hospital soon kalau you're worried, especially if the fast heartbeat is consistent atau ada simptom lain macam kesulitan nafas or baby nampak lethargic. A few of us mums always trust our instinct, kalau rasa ada yang tak betul, jangan tunggu. Better safe than sorry!
