Hi! Sorry to hear about the constipation, sobrang frustrating yan, especially when you're trying to find the right formula. Hindi ako nakapagtry ng Bearbrand Jr specifically, pero a few of us sa circle tried switching formulas kasi ng same concern, at nakita namin talaga na different brands affect babies differently, some caused less constipation, others worse. Since constipation sa formula change is pretty common, I'd suggest checking with your pedia first para makita kung this is just adjustment period (usually 1-2 weeks) or if the formula itself doesn't agree with baby; they might recommend something gentler or suggest adding more water/hydration. Hope baby feels better soon!
