I wouldn't give it any thought either... with Izzy I was told she would be a "good size" and at 11 days OVER she was 8lb 13oz, big not huge! This time around at 41 weeks I was told that bub was "average" going off a scan and he was 10 pounds with a massive head!! Not soemthing you can control and our bodies know how to make babies perfectly sized for us so enjoy and good luck!!!
