On-call Babysitter Needed For 8 Month Old In Bellingham

We have a nanny, but we are looking for someone who can be with our son for an hour or two at a time so we can go on dates sometimes. Looking for potentially availability (with probably one or more weeks notice) in the afternoons, evenings, and/or weekends. In the evenings he would probably already be asleep for the night. Otherwise we would try to schedule around his naps (he can take stroller naps with a caregiver). We also have a neighbor friend who has a baby girl the same age as our son. They would like someone when she has meetings scheduled and doesn't have other care lined up. This posting is for someone who could be on-call babysitter for both of us, our neighbor friends with first priority, one baby at a time (at least to start). We look forward to hearing more about you. Thank you!!
