We will be going out to dinner and will need someone to stay with our kids. The eldest is 3.5 years old and she loves boardgames and for you to read a book with her before bed. The youngest is a 7 months old crawler and will be asleep when you arrive. You may need to feed him a prepared bottle if he wakes himself up (unlikely), but will go back to sleep immediately after that.
The dog is going to sit at the window and look for us to get back, but can be left in our room if there is any concern. She will be fed before you arrive.
