Part-Time Nanny For Our One Year Old

I work from home and just need assistance taking care of our son during my work hours 2-3 days a week, days may vary. I can step away and help with meals and will usually take him to put him down for naps if I don't have a meeting scheduled. I'll be around and available most of the time, with just occasional meetings I'll have to shut my office door for. We have two cats and two dogs. The dogs will be outside or in a separate part of the house while nanny is here.
