Mama, kailangan mo munang tanungin ang pedia mo about that bago mo gawin, every baby's different, and vitamins while breastfeeding need a doctor's okay! One of my mum friends asked her pedia din about supplements para sa baby, at sabi niya okay lang mag-consult muna before starting anything, kaya go lang sa checkup. Your doctor will know best what baby needs at this stage, especially since mixed feeding ka na. Let me know what pedia says!
