I imagine if you planned on bfing them for.the first year at least the baby would need to live with mom. Maybt if mom works dad could have an opposite schedule so he could be the caregiver.
Lots of women are single mothers and coparent with their ex so its possible. Living apart isn't ideal but for moat its not a choice.
