Ay, honestly kami nag-start ng zinc supplement sa anak ko around 6 months na, hindi pa 4 months, kaya better check with your pedia muna about the timing and dosage specifically for your 4-month-old! A few of my mum friends give it, pero lahat sila sinabi ng doctor nila muna kung kailan and how much, kaya really important talaga na i-confirm with yours para safe sa baby. Kung concerned ka about immune support or deficiency, definitely worth bringing up sa next checkup mo!
Kami naman gumamit ng zinc supplement para sa baby ko around that age din kasi daw it helps with immune system, pero honestly best to check with your pedia first kasi depende sa baby, kung may deficiency or kung okay na siya sa diet, bago magstart ng anything, ganun talaga pag 4 months pa lang.
