Babysitter - Full-time / Part-time

Looking for a weekend nanny for a 3-year-old in Shadyside. This would be at least half of one weekend day, but ideally one morning and one afternoon (doesn't matter which is Saturday or Sunday). We also have a 11-month-old who may join the 3-year-old for activities later in the summer, but for now (and the foreseeable future) this is just to help with getting the 3-year-old out of the house for more activities.
