Hello and Thank You for using Just Answer. It is a true delight to have such a happy and healthy baby as you do. I praise you because her happiness is a reflection of the time and effort that you spend with her. Right now, she is very much attached to you. It would not be a wise idea to cast your daughter off to her dad right now, especially with the breastfeeding issue. It is great that you have given the dad the option to visit as often as he wishes now and things will change when she is three. Dad must realize that your daughter is not a toy. She has 24/7 needs. If he works at night, would his roommate watch the baby? I would hope not. Your course if action seems to be right on track. I do agree with your plans. However, just to warn you that nowadays many dads who are no longer with the child's mom get on a power trip and will take the mom to court which is a process that is costly and drags on forever. So I hope that your can settle your differences without involving the legal system.
Much success to you and your little angel.
