Aww mama, I feel you, hindi madali ang formula journey pero kaya mo yan! Honestly, ang best move is makipag-consult sa pedia mo para ma-recommend ang formula based sa baby mo specifically, kasi bawat baby different talaga sa needs nila. A few of us tried different brands and what worked sa isa, hindi sa iba, marami ring factors like tummy sensitivity at allergy. What I can say is look for formulas na may DHA/ARA, and usually yung premium brands or Follow-On formulas (0-6 months) are formulated para sa healthy growth, pero talaga best na i-discuss with your doc kung ano ang most suitable para sa little one mo. Kaya mo, mama, you're doing your best!
