She was thin , and sick often , never really ate much and super susceptible to the cold . I fretted over her for the first year or so , but when it seemed like I could give her the same routine I was giving Alex , I slipped into that . And obviously , that 's worked for the last year and a half .

Question: Why may she have been thin and sick ?
Answer: Because she had the same routine as Alex .Because she slipped .She did n't eat enough .Because she was cold .
