Nanny Needed - Full-time / Part-time

My son is only 3 months old so he mainly eats and sleeps with a little developmental activities sprinkled in throughout the day. I am looking for a remote job so once I start working from home I will only need 4-5 hours a day. I am currently planning to go back to the office to work so the nanny will be on their own for 9 hours a day to start. We do have a cat and a 9-year-old German Shepherd mix. Both are super sweet, good with people and the baby.
