Many new moms returning from maternity leave feel trapped between conflicting roles: enjoying an intellectual challenge (and bringing in an income), and leaving their tiny babies with a hired caregiver. While there's no reason to feel guilty for making the decision to be both a mother and pursue a career, if you're not ready to commit to a full-time position, working part-time can be a practical way to experience the benefits of each. As well as helping you stay relevant in your field, a part-time job can provide mental stimulation, boost self-esteem and give you a much-needed break from the constant demands of being a new parent. Add all that to the fact that you love your baby to pieces, and you've got the makings of a first-class mom.
