What do you think of this situation?
I started a new job this Monday and left my DC 3 at home in the care of an educator with 20 years of experience working at a daycare. DC 5 to be picked up from school in the afternoon.
Monday: I get home at 6. Kids have been watching tv all afternoon (over 3h!!) and DC3 had ice cream for lunch.
When I ask educator about it, her response is "I told you so", looking at DC3.
I am shocked, so on Tuesday I leave the TV unplugged and my DC3's lunch cooked and served in a plate in the fridge. I instruct DC3 where her food is (I trust her more than educator) and DC5 that he can play after school but not allowed to watch TV.
At 3:30pm educator write to tell me that DC3 didn't eat. As I leave work I call DC and hear the TV on the background. I ask DC who plugged the TV and they say DC5
Then I ask educator who plugged the TV and she confirms it was DC5. I ask her is she doesn't feel embarrased! And I hung up since I am so angry... 
Then I decide to go through my security camera footage. It is in the living room, I talk to DC through it and educator is aware that it is there. I find DC sitting in the sofa watching TV again (main floor) while educator is in the basement talking on the phone. She then comes upstairs and starts screaming at DC: "again? You are watching TV again? Did you hear your mother? She was going to hit me!! She almost hit me" All this shouting, and mind you that we had talked in the phone and I was obviously angry but not even home, how the hell I had almost hit her????
