Girls, hi! Such a situation: the son watches cartoons on TV, mainly Baby Shark and Three Little Kittens - to the cot was indifferent, could look at photos together, videos about him. On the cot in YouTube I put before bedtime audio fairy tales and then somehow saw a blue tractor ?? watched for 10 minutes. And from that moment began nightmare. He sees the cot and demands "tra tra where?" I can't take the phone even call immediately hysterics and on the floor ?? Like a zombie to this tractor. While in the toilet climbed up the shelf and took the phone himself found it. And everything can't take away. Other cartoons we offer him he doesn't want, only the blue tractor
