Everyone tells me not to worry because she's a big baby so she's obviously getting enough to eat but I'm her mother and it's my job to worry . I'm very good at my job . After dinner though , I let Charlotte walk around with me holding her to steady her . She's gotten so good at taking steps recently .
Why does the writer say she is very good at her job ?
