Sorry for the rubbish title..
My 5 month old DS has never been able to hold his head up straight for more than a few days after which it will drop/tilt to either the left or right side, after a couple of weeks the tilt will correct but then a few days later (sometimes only 1 or 2) his head will drop/tilt to the other side. THe tilt is not very severe most of the time, but occassionally he has short periods (maybe 10 or 20 minutes) where his head drops completely so that his ear is resting on his shoulder and he can't move it at all, this severe tilt usually corrects itself after a nap.
He has been having physio for 3 months now but the physios have admitted that they have no idea what is going on and have never seen anything like it before. They have ruled out torticollis as that usually only makes a child's head drop to one side and they seem particulalry confused about why it corrects and then drops again.
I work with children and have never heard of anything like this (nor have my colleagues)
We are seeing a paediatrician at the end of the month and I'm hoping she can shed some light on it but in the mean time do any of you have any experience of this? Or any ideas of what it might be?
