In reply to felt:
If this is a joke (and a good one at that), then please just pity me.
If not, then it would appear that your GP is seriously misinformed and needs to become familiar with advice provided by Public Health England. See point 2 in the following:

Apparently lack of awareness by health professionals is a major issue here in the UK, which can and does lead to missed or wrong diagnosis, delayed treatment etc.
"Unfortunately UK consultants see few Lyme disease cases and experience is spread thinly across the UK's GPs. Although there are plans for a national clinic, the NHS has no specialists in Lyme disease." Quoted from:
http://www.lymediseaseaction.org.uk/about-lyme/treatment/
Fortunately, my GP was more aware and, based on the appearance of the bite area 2-3 weeks after being bitten by a tick during a day's climbing in the Rhinogydd, I'm currently on an extended course of Doxycycline, hopefully just as a purely precautionary measure.
Apparently, less than 10% of UK ticks are infected with the Borrelia burgdorferi bacterium which causes Lymes, so the chances of being infected are low, especially as transmission to the host doesn't happen unless the tick has begun feeding. Nevertheless, it might be worth keeping a close eye on your little one just in case he/she starts to show any symptoms. Better to be safe ... etc.
