Does anyone have any experience of this? The last couple of days my 9 month old has been twitching her head to the side, with her shoulder coming up at the same time. It’s quite jerky and definitely involuntary. Doesn’t happen all the time just occasionally. But in little spurts of a few at a time. Any ideas? She doesn’t have any health issues or seem to be bothered about it. I think she might have been squinting her eyes a bit too but I’m not sure about that. Any advice most appreciated.
