Dear Amy: I am a married mother of a 2-year-old, and a 5-month-old baby. My husband and I are both professionals, and I am currently on parental leave. My husband’s is the “primary” career in the house, and he earns a lot more than I do. I am happy taking care of my little ones, but I am still getting up three or four times a night with the baby and getting progressively more tired.
