Is there a big psychological effect if sometimes you don't let your toddler "dede" from you?

I saw an article and research about it which says that breastfeeding is a special bond between you and your baby. So aside from that bond breastfeeding has so many advantages over formula milk. Increases IQ, brings you closer to your child, your baby will have stronger immunity against diseases and more. Mas lumalaking close ang bata sa Nanay niya pag matagal na-breastfed ang bata. Proven by Science.
