Hi mama! For brain development vitamins, marami kaming inaaral dito sa group, DHA is really important talaga, so look for one with omega-3 or specifically DHA + ARA combo na safe for 1-year-olds. A few of us nag-pair din ng Cherifer with separate DHA supplements like Nordic Naturals or other trusted brands, pero honestly best mag-check lang sa pedia mo kung anong specific combination ang best for your LO since may iba't ibang formulations at dosages depending sa baby. Good luck, mama!
