27+2 weeks 4D scan

Samantha • Mummy to my beautiful Archie born 13th September 2015 👪💘
Just thought is share my little boys picture. He wouldn't look face on to the camera but we did see him sucking his thumb, crying, swallowing and sticking his thumb. My boyfriend is convinced he looks like him. 13 week and we'll know. 
The sonographer said he is already head down...is this normal?
