Whistle sound sa paghinga ni baby

Hello. Your baby is fine momsh, don't overthink. Baka ready na kasi siya lumabas kaya nanganak ka at 35 weeks. SKL. May cousin in law 35 weeks din pinanganak nasa 2.8kg and considered full term na upon check-up. My baby naman was born at 37 weeks 2.4kg, and shes also healthy baby. Normal lang po yung whistle sound. At normal din mag halak ang baby esp pag overfeed. What I did to my baby before after BF to prevent halak, pinapaburp ko (although hindi naman daw need sabi ni Pedia dahil BF), hindi ko siya pinapahiga agad, kinakarga ko ng medyo naka upright for 15-30 mins, para bumaba pa ng husto yung milk at hindi mag backflow.
