The mother's bond is born of biology. This baby grows inside her body, and is nurtured from her body. If a mother is unable or unwilling to nurture her baby, and be this primary attachment figure, then certainly it would be important to see if the father is able and willing to fill this role. However, it is important to recognize the importance of babies having a mommy AND a daddy, not a mommy OR a daddy. The best way to protect the breastfeeding relationship in a family law case is to keep anger out of it, recognize that the baby needs a bond with both parents, and work together for the child.
Parents can settle their cases many different ways.
And you can have visitation that really works for your child by settling. Letting a judge decide a case is often like playing lotto. Help your child to have a good relationship with Daddy. Keep things flexible. One of the easiest ways to lose your family law case is to go in very angry, bash the other side, and try to restrict or supervise the other's access to the child.
