I hope you still try. My son is 16 months and will only breastfeed. The longer you can breastfeed the better for him. I went back to work when my son was 2 months old. I know how trying it is, I teach kinders all day and then go home to him. Sit in a rocking chair if you can and just be with him. There is only have a short time in his life that you can do this and have this bonding with him. It's good emotionally and well as health wise for both of you.
Keep trying. You both deserve this special time together.
