I was able to bond with all four of my children without a problem. Our three oldest children were biological and breastfed. Our youngest one was adopted and she is formula fed. We have bonded with all of the children. My husband has bonded with all of the children. And the children have all bonded just fine with each other. Our baby, our youngest child, was able to bond more so with her siblings being formula fed since they were able to share in the process of being able to feed her. Other family members as well. When you are breastfeeding only, it´s harder for other family members to step in during that point and help with the process. It is currently a shared process for our family since she is formula fed and on the bottle.
