Hey mama! I totally get it, Enfamil is sobrang mahal talaga A few of us tried switching to Lactum because it's gentler on the tummy and mas affordable, and some babies with sensitive stomachs did okay naman, pero honestly kailangan mo ring observe kung paano mag-adjust si baby sa bagong formula since bawat baby talaga ang reaction. I'd suggest checking with your pedia first before making the switch kasi alam nila best si baby mo, and then try yung Lactum or Bonna gradually (mix it with his current formula muna for a few days) so hindi shock sa system niya, usually nakikita mo agad within a few days kung okay ang bagong formula or need mag-adjust pa!
