Hay thanks Roscoe for your feedback. Muchos gracious.
Worth asking though as DS is my "one off" child.

Born at 41 1/2 weeks, home birth, bellowed like a bull, apgar 9.....rushed to SCBU 8 hrs later with respiratory difficulties. 8 days later diagnosis, hylin membrane disease ( atypical premature lungs - almost unheard of !) Also experienced a never before reaction to pain relief post-operatively. BP to stroking point.....He does seem hyper-sensitive to drugs (gastro. had never had to withdraw anyone off Pentasa for anxiety attacks !)Will keep an eye on him, but I think you are right.
Anyone else had probs ?
