Hi,
Our 2.5 year old boy is in pre-school from 09-17. Due to my work travels and my wife's job, sometimes we'll need assistance with babysitting in the early mornings 07-09 and late afternoons 17-19, plus the occasional full day in the weekends. They boy is pretty easy-going, just need some snacks and playtime, and be taken to/from his school which is a 10 minute walk away from our house.
Great if the babysitter speaks English, but otherwise Spanish/Catalan is good also.
