Hay mama, nakaka-stress talaga yan lalo na sobrang open sa pagkain ang baby mo! Honestly, since hiyang sya sa Similac TC at sobrang comedic ng poops issue mo with the other brands, I'd suggest sticking with TC muna habang nag-eexperiment, a few of us tried jumping straight to regular milk and naging mas complicated pa, so maybe try mixing regular milk with the TC first (like 1oz reg milk + 6oz TC) for a week or two, then gradual increase the ratio. At 16 months na sya and eating everything, pwede mo nang i-integrate ang regular milk sa food (like sa lugaw, luto, or drinks) para kahit slowly, nae-expose sya, then phase out the bottle formula eventually. But honestly mama, since nag-persist yung pooping issue across different formulas, worth checking with your pedia bago mag-experiment pa more, baka may lactose intolerance talaga o milk protein sensitivity pa, and they might have better suggestions based sa baby mo specifically!
