Nanny Needed For My Children - Full-time / Part-time

We have two twin infant boys. We'd like someone who'll be able to handle both throughout the day. Must be able to play with them and help them develop as they grow. Must speak Spanish, although we do speak English natively as well. Must be able to go on short walks with them to start the day before the sun gets too strong. Please clean up after yourself. The boys are too young to make messes, but they will eventually reach that stage, so must be able to clean their messes as well.
