Flexible Care Schedule In CR Meadows For 18m Old And 5yo

My husband and I are looking for intermittent care for all three of our children (18m, 5y, and 14y). We don't currently have anything specific on the calendar, but would love to find someone that could watch our 18m weekly for a couple hours (specific day is flexible, and is flexible week to week), help out more hours when my husband travels for work (travel dates TBD, but roughly 1 week at time every month), watch our 18m during the day if I'm ever out of town (possibly 12/9-12/13), and overnights for both kids if my husband and I want to get away for a few days (we don't have family that lives in town). We'd love to find someone who feels like another member of our family, and who can remain with us for the foreseeable future. Must be comfortable with dogs (we have a friendly lab mix).
