Occasional Sitting For Two Very Easy Going And Calm Kids!

We have two beautiful kids, a girl(18 months) and a baby boy (4 months). Getting to appointments can be hard with two kids so we are looking for an occasional sitter to stay home with one while I take the other to an appointment. Sometimes they both have appointments so this person needs to be willing to come to appointments with me and the kids to give me an extra hand. I occasionally also work in the evening so we'd need occasional care in the evening until my husband gets home. We'd also need a reoccurring sitter for monthly date nights. Our daughter only speaks Portuguese so someone who speaks Portuguese is a priority. Our son (4months) is currently into tummy time and playing on the floor. Our 18-month-old is into playing at the park, "reading" aka looking at books, and interactive play.
