Seeking backup care for toddler during daycare closures/ minor illness/ teething

We need to build a network of backup care for a one year old boy when daycare is closed and/or he has minor illnesses (such as teething, low grade fever, etc). Mom and dad work from home but need someone as primary care to handle playtime, manage naps, heat pre-prepared meals and snacks. If you love working with young children and can commit to occasional work days (likely short notice), we would love to hear from you.
