Babysitter Needed for my Children - Now Hiring

We are a two corporate mum household. We have a toddler of 2 years (girl) and a newborn (boy). The job will be to support the mums with one kid interchangeably. 2-4 days a week to help with the newborn - supporting feeds and general maintenance of his things. Possibly doing drop off or pick up of the toddler from a local daycare but never at the same time as caring for the newborn. The role can expand depending on the mutual comfort of everyone involved.
