Nanny Needed For My Children - Full-time / Part-time

Need help with basic infant care. Child is 4. 5 months old and wakes around 9:00 a.m. My mother will be at the home as well, but she is currently injured and cannot take care of the baby. He is formula fed at the moment and eats around every 1. 5-2 hours during the day. His wake windows are around 2 hours right now, so he will have 4-5 naps during this time. His naps range from 30 mins to 1. 5 hours.
