These kids are 3 1/2 and mom is specifically mentioning they are capable of communicating as though it were some unheard of skill in a child that age. Also at 3 1/2 only 1 child is toilet trained. Absolutely sounds like at least one of the kids and possibly both are neurodivergent. The casual couple requires the hire to live in yet have their own transportation. Most likely they'll be expected to share their vehicle so the couple can commute to work. They are also interested in someone who likes to cook. Translation the hire will be cooking the family meals. The new hire must also not have anyone significant in their life. Which gives off trafficking vibes, can't have anyone wondering why the hire hasn't been in touch while they live in the basement and work for free.
