Hello pretty mums, I intended to do exclusive breastfeeding, but my boy didn't suck 5days after delivery due to my kind of nipple as dey say so I feed him with formula after I was advised here to, my question now is, he has started breastfeeding now, can I still do exclusive, remember I feed him formula and my mum was secretly giving him water in my absence. If no will he be in any health or intellectual danger because of it.
