Babysitter Needed for my Children - Full-time / Part-time

We are looking for a nanny for two 2-year-old girls. Looking for 8 a.m. -12 p.m. 3 days a week, with 8-12 possible extra hours with just one child for the next year, but we can be flexible with hours. We have two golden retrievers so must be comfortable with pets. Offering guaranteed hours. Parents work from home in a separate part of the house (out of sight and hearing distance from child) One child has a dairy allergy. Home has cameras. Previous experience preferred. Must be vaccinated
