Thanks guys for the replies,

I went for the scan Thurs arvo and was told that all the critical factors were 'perfect' and all is symmetrical which is fabulous. Amniotic fluid a bit less than 50th percentile but apart from that all well. Baby 'measured' 5pds (but we all know this can be highly inacurate) but would put bub on track to be about the same size as DD 1 (6pd, 9oz) at term.

Just a waiting game now......but not a stressful one.
