Babysitter - Full-time / Part-time

We are looking for a sitter/mothers helper for Fridays in Valencia. We have 3 kids ages 3mo, 2 years and 11 years. The 11-year-old is with us every other week and will go back to school in August after summer break so he's more temporary. Need help tag teaming the littles as one parent is going back to work 6/16, and the other parent is not enough hands! We have 2 small weiner dogs. The youngest is wait listed for daycare so the job may ultimately only be the 2-year-old in a couple of months. Hours could vary 9-6 or 10-7 we can talk. 2-year-old sleeps 130-430, baby varies. Need help in eve watching kids so parent can do dinner etc. and entertaining them so the house doesn't fall apart :)
