Ay, switching formula can be tricky talaga! Pero ito talaga dapat tanungin mo sa pediatrician mo para sigurado sa exact oz at scoops, bawat brand may kaunting differences, at importante na tama ang ratio para sa baby mo, lalo na at 3 months pa lang siya. A few of my mum friends did similar switches, at ang advice nila palagi ay gradual transition, hindi bigla bigla, pero definitely doctor's guidance muna bago mo i-adjust. Rooting for you and baby mo!
