Good night. Girls, I'm really worried that he's spinning like a top at night, where his head is feet and so on. Maybe something bothers him or is it normal? Such behavior has been noticed for about two weeks now. He probably doesn't sleep well because of this. Here I look at him, spins and spins, only freezes and then again... And he flips over onto his belly and pillows are piled up around him, blankets are poked in, he'll move everything ?
