Uy, mama, if baby is vomiting like that three times in six hours, especially with large amounts, please take her to the doctor or ER right away, okay? Hindi yan normal at kailangan tingnan ng medical professional agad. A few of us mums have gone through milk-related concerns, but this one really needs expert eyes, lalo na with that amount. It could be something that needs immediate checking, so don't wait. Sending you strength, and I hope baby feels better soon!
