we have 2 kids (3 yo and 21 months old) who are at school or daycare all day.

we need someone to help with the house in the evening, from 5-8, 3 days a week.

Some of the job description will include:
Folding the laundry and putting the clothes in the cabinet
Load and unload the dishwasher
Light cleaning including brooming and wiping the kitchen floor after the kids are done eating
Tidying the play area after the kids are done playing
if she is good with cooking we might also ask her to cook for us from time to time.

ideally if she ends up getting along with the kids, we would also ask her to stay with the kids for a day or two if they are sick and cannot go to school but this is not a must.
