Hi! Based sa kwento mo, totally normal yan, babies on formula often go through poop changes kapag bagong brand dahil different ang composition ng milk, so it makes sense na bumalik sa normal consistency when you switched to Lactum. The watery poop (pic #1) could've been signs ng mild adjustment or sensitivity sa Bonna, so good call mo na nag-switch! A few of us moms noticed din na ang poop consistency ng babies really changes with formula changes, kaya if pic #2 is back to normal and baby mo's happy, comfortable, and gaining weight well, then you're doing great. Just keep an eye lang if may other signs like fever, excessive crying, o hindi tumitigal ang watery poop, then best to check with your pedia to be sure.
