Thanks bjrose, i thought of that also, its pretty full on, it is red on white, some raised some flat.
The antibiotics dont seam to be working well though, he is still quite chesty and wheezy.
He started them last mon, he has 3ml twice a day, its called maxamox suspension, it contains amoxycillin.
He has finally fallen asleep.

Edit. He has just woken screaming and his rash is even worse, made a dr appointment, but its not till 3.
