My ds (7+months) has just got his 1st tooth and 2nd on the way. These seem to be causing him considerable pain and night waking, just about manageable with calpol. He has also started throwing up a bit and he has never been a sicky baby. For the last few days it's been getting more frequent and smellier, i.e. proper sick rather than posset (is that the right term?). Do teething and sickness go hand in hand or has he got two nasties at once? He doesn't seem ill as such but it's very odd for him to be sick.
