Occasional Backup Sitter

Hi there, Jack is an amazing 10-month-old little boy. He is such a happy, loving, playful guy! I work from home, he is in daycare 2 days a week and stays with one of his nanas 2 days a week. Mondays he is typically home and I generally can handle working with him home, but sometimes could use some assistance for a few hours (could be a different day of the week occasionally.) I am looking for someone who is flexible so that when his childcare falls through they are able to assist sometimes last minute. I will try my best to notify the sitter days in advance!
