Similac Infant Formula vs Tummicare HW

Hello po, ask ko lang po my baby is 1mo and 2wks pa lang and I'm away for work. He is used to latched the Similac Infant Formula 0-6m but iba yung nabili ng inutusan namin which is yung Similac Tummicare HW 0-12. Pwede naman sya papalitan but I'd like to know if ano yung difference ng dalawa if the tummicare is way better ba or di sya pwede ibigay kay baby for his age or what. Your answer is very much appreciated po. Thank you po.
