Part Time Babysitter Needed for my Children

I am looking for a part time nanny for my daughter in January. She will be around 4months old. My mother-in-law will be helping a few days a week but I will need the days she can't be here to be filled. The days are not set in stone on when she will be helping. I also have a 4-year-old who goes to daycare that won't need any care. We have one cat and she is an inside outside cat
