Thanks for the support and suggestions girls... I'm just getting so exhasted from his antics I just dunno what to do with him

Ido as you suggested Shell, and put him in his playpen just to get a toilet/shower break, but it's not much of a break when all you can hear is screaming. I can't even put him on the floor whilst I stay in the same room (like the kitchen whilst I'm cooking or when vaccuming)

Hmmm.. maybe it is another tooth.
