Has anyone experienced this? Baby is one month and two weeks old. Lying on their stomach rests only on one hand, the other is free (can raise it calmly, wiggling. And therefore, as there's support on one hand, they fall over onto that side on their back. I read about torticollis, but there are no more symptoms from that. But here's the question: can this be torticollis or just because they rest on one hand like this? And if it is torticollis, what should I do to make it go away? I have an appointment with the doctor on the 28th, so I can't even ask her yet.
