In the beginning, Mama Chang cares for each individual infant herself; this offers her a chance to get to know new residents and teach others (like the new mothers) to care for the babies. She also hires professional nurses in her clinic.
她相信，要照顧產婦和新生兒，需有專業的護理知識、技術和經驗，因此她聘請的三位育嬰室工作人員均有護士執照，其中兩位且擔任過醫院育嬰室主任。
