Thanks Willow. I am going to my GP tomorrow for his 6 month needles so I'll get a referral then. I think you are right about the teeth, he has started pulling at his ears which mum tells me can be related to teething. I'm going to get the GP to check him over for an ear infection etc tomorrow and if that is ruled out then I think it might be the teeth. He slept better last night (I sat in his room and sung until he drifted off) so here's hoping it is only temporary.
