Aw, ang hirap talaga ng ganyan, lalo na first time mom ka pa! Pwedeng overfeeding, pero mas madalas yan sa babies na naturally prone sa reflux or sensitive ang stomach, a few of us here noticed our babies ganyan din, especially if they're gulping too fast or nakakatulog agad after feeding. Try offering smaller amounts more frequently na lang, at let her burp in between feeds, kasi yung air bubbles talaga ang culprit sometimes. pero since patuloy pa rin siya, mas better kung i-check mo na with her pedia to rule out reflux or allergies, para ma-guide ka ng tama on how to handle it, ate.
