When my nephew was born I was at my sisters house every single day helping her care for him because her df is useless. plus, she is very insecure and uncomfortable with her ds. When she went back to work at 6 weeks i became his full-time nanny, about 50 hours a week. I also go over her house a few nights a week to spend time with her, and always end up taking full responsibility for my nephew. i love him like my own. The problem is I feel guilty because i want him to have all of his "firsts' with me. i know that is terrible but i hate missing things with him, as i would with my own children. Am i a bad sister because i secretly want this!
