I didn't have any growth scans, but at 20 wks with my first, he was measuring 22 weeks - he came out on 90thish percentile and has stayed that way.

He was 9pd2oz and 56 cms long.

80th is not HUGE , and growth scans are not always that accurate as you have probably seen from feedback and info from other BB'ers.

My subsequent bubs have surprisingly been smaller at 7pd14oz (DD) and 8pd1oz (DS#2)!!
