Hi mama! Sa Bonamil, ang standard measurement talaga ay 1 scoop to 2oz ng water, kaya para sa 4oz ay 2 scoops lang, hindi 4, a few of us actually made that mistake at first kaya I'm glad you asked! The yellow scoop na kasama sa box ay designed specifically para dyan, so make sure you're using that and leveling it off properly. If the instructions sa back ng box ay unclear, you can always check the tin itself o mag-call sa customer service nila, mas safe yan kaysa mag-guess. As always though, worth double-checking din with your pedia kung may concerns siya about baby's digestion or poop consistency, lalo na if you're noticing changes!
