Aww, I totally get the worry, formula transitions can be so tricky! Honestly, 4-5 poops a day at 6 months isn't unusual, especially kapag nag-switch lang kayo ng formula dahil may adjustment period talaga ang tummy nila, pero since nag-improve na with Lactum at no signs of dehydration, that's a good sign na nag-settle na siya. A few of us tried different formulas din kasi sa aming babies at napansin namin na it takes around 2-3 weeks for their system to fully adjust, so maybe give Lactum a bit more time to see kung mag-normalize pa ang frequency? That said, mommy, I'd still suggest bringing it up sa pedia sa next check-up lang para ma-confirm na everything's okay with his digestion, doctors like to know these details especially pag may recent changes
