Baby vitamins/supplements - worthwhile?

Zaza

Because I breastfeed my 16 month baby, I take pregnacare.

Atm baby has daily vitamin d drops.

I’ve seen something called Wellbaby, part of vitabiotics,the same company that does pregnacare. Wondering if it’s worthwhile having baby take that? Will it be beneficial to baby? Anyone give / gave their baby vitamins / supplements like these?
