Thanks all for the advice on kids being present at scans. Thankfully I have realised that the scan is a Wednesday which is great as that means the bear is in nursery. Phew.
Keeping quiet, still and well behaved is not his forte. I keep remembering back to my time in Hong Kong where toddlers behave immaculately, even on the busy MTR during rush hour they never seemed to kick off and wonder if he could benefit from a cultural exchange for a month or so!!! Pennie am I being overtly nostalgic or is it true that the Cantonese kids in Hong Kong just seem to be so well behaved (I guess because of the cultural emphasis on obedience and discipline)? Is that quite a pressure to be around if you have a more 'normal' willful toddler?
Jonas would appear like some kind of rampaging Visigoth in comparison he really would
. I blame my Dad's Genghis Khan genes (he hails from the Polish / Ukraine border and the entire family over there reckons he's a throwback to the Mongolian hordes who got as far as Eastern Europe). Mindst my entire paternal family has a tradition of rebelliousness and generally being contrary wee fecks. 
So yeah. I'm glad he's not coming to the scan!
