Part Time "Live-In" Care Needed!

Hello! I am a single momma to two pretty awesome kids, 7 and 4 years old. I am active duty military and my job is starting to require that I works overnights and do some traveling. I need someone who is willing to do somewhat of an unconventional "live-in" situation for the times that I have to leave. Im hoping to establish a relationship with someone that can do some evenings and/or weekends to better get to know the kids so that when I do leave, they are comfortable with you. I know this is weird and not necessarily a full-time position, but I'm willing to work with you to see if we can figure out a schedule that works for both of our needs. Thank you!
