ds is 14 mths and is teething badly, unsettled, not napping well, and pressing his bottom gums all the time. last two nights he has been sick in the night, but not during the day. he is eating ok, just off his milk a bit. seems fine in himself, sure he hasn't got a bug, but don't know why he is being sick in the night/ early am. he has just whimpered in the night, and is not making himself sick crying. has anyone found teeth coming through has actually caused sickness??
