Eh, normal je baby 2 bulan macam tu, banyak babies ada reflux atau just learning to feed pa, so mual-mual itu part of the journey lah. Tapi kalo muntah banyak sangat or baby seems uncomfortable, memang better check with your pediatrician sebab sometimes ada deeper issue macam tongue tie or overfeeding, pastu doctor boleh proper assess. A few of my mum friends' babies yang sama stage, tapi yang penting observe la, kalo baby gaining weight okay, active, and happy between feeds, usually nothing to worry about, tapi kalo mual tu consistent or ada changes, jangan delay to see the doctor ya!
