Childcare Needed - Full-time / Part-time

We have 3 children, but I mainly need help with our 5-year-old. My husband leaves for work between 4 & 5 AM, and I have a newborn and narcolepsy, which makes it difficult for me to wake up with this child around 5:00 everyday. If he does not get one-on-one attention, he gets into things around the house or watches TV for hours on end, both of which set us up for a tough day ahead. I'm looking for someone who is willing to come for a few hours in the early morning to play with him, feed him breakfast, and keep him entertained until I am able to get on my feet.
