My 7 month old seems very unhappy this morning. He's been low-level whingeing for a couple of days, but this morning it's constant groaning, wailing and shouting. He's rubbing the top of his nose and inner eye a lot with the back of his fists, and doing some ear pulling too.
Is this teething? His lower incisors came through without too much fuss about three weeks ago, so the upper ones are due.
