Aww congrats sa one-month-old mo, mamsh! At one month, typically around 2-3 ounces per feeding (or 60-90 mL) is the ballpark, but honestly kailangan mo talaga ng guidance from your pediatrician kasi bawat baby ay iba, some babies are just hungrier than others at wala namang masama doon. The fact na laging gutom sya at lumalungad sa bottle, baka naman kailangan nya talaga ng more milk, or maybe she needs a nipple flow adjustment if breastfeeding, so best to bring this up sa check-up mo para ma-assess ng doctor if she's gaining weight properly and if you're feeding her the right amount. A few of us moms swear by pacing the bottle feeds (tilting the bottle more horizontal, letting her pace herself) kaya hindi automatic yung gulping, pero talaga the pediatrician can give you a feeding plan na specific sa baby mo. Kaya mo yan, mama!
