Not really sure there's an issue but I'm a little concerned as it just didn't seem to bother her. It was clearly just phlegm accumulated overnight and she's perfectly well in herself so I'm not worried about that.
But I'm concerned about the sleep-vomiting. She's past 10 months and quite capable of changing position in bed, but she didn't. Any bright ideas? Or am I just being a bit PFB; after all, she dealt with it...
