Babysitter - Full-time / Part-time

Hi! I am looking for someone to watch my two daughters (8mo and almost 4y/o) at least two hours and up to four hours every Tuesday and Weds. I will be home majority if not the whole time but I need a babysitter who is comfortable with this age range while I am able to do chores, run errands, etc. Spanish speaking and previous experience taking care of infants who are exclusively breastfed is preferred. Thank you.
