Sayang, jantung laju pada bayi boleh jadi normal or tanda something else, you really kena go see the paediatrician or go to clinic/hospital to check, especially if it's happening every morning like that. Better safe than sorry when it comes to baby's heart! A few of us mums have had similar worries, and the doctor always say the best thing is to get it checked properly so you can have peace of mind. Jangan risau, doctors see this all the time. Please book an appointment with your paediatrician soon, okay?
