Babysitter Needed

We are looking for an engaging and reliable nanny for our sweet 2-year-old son for 2 days/week. We also have a 4-year-old daughter, who is in preschool. We are expecting another baby in November and I will be on maternity leave until March, at which point we would need help with our 2-year-old and the baby. So we are looking for someone who is willing to commit for at least a year. The days will be Monday and Thursday as my retired Mom is watching them on Tuesday and Wednesday. I work from home, except for when I need to go into the office for an event. My husband goes into the office for work. We also have the most gentle and sweet Cavalier King Charles Spaniel.
