I have a very miserable little baby here. He's been off colour for a while so I took him to the GP... Anyways it seems like he has started teething. He's got white bobbles on his top gums and he's biting his fists and clawing his face. At this moment he is screaming in my ear inconsolably, when he's not screaming he just lays his face on my shoulder, first one side then the other and looks at me as if to say "why are you letting this happen to me?". He's all calpoled up but still in pain. What can I do for him? how long will this last? He seems too little to be getting teeth, he can't even pick up a toy to shove in his mouth.
