Hi my 9.5 month old son has done this 3 times already and each time I have taken him to the GP who says leave it a few day to see if it gets better..... Last time he did this was over a month ago and after about 5 days he holds his head straight again. He still moves his head around all over the place, but it's to one side. Has anyone come across this before. I am taking him again to the GP after work today, as I have looked on line (always a bad things to do) and have read some horror stories about tumors etc on the neck etc...... Could he just keep pulling it or just being lazy holding it up??? I would like the GP to send him for more test to make sure his necks okay. Any advice would be very appriciated as getting very worried now :-(
