I have a 4-month-old girl and a 19-month-old son. Job would be 9-5:30 on Tuesdays and Thursdays.
I have two Labrador retrievers as well :) "Light housekeeping" is SUPER light: wash bottles, load dishwasher, pickup toys... maybe sweeper the floors occasionally or throwing things in my crock-pot. VERY minimal! Mostly just cleaning up after yourself. We aren't expecting a maid. Just someone to love the kids!
