Ours did exactly the same! Laid on it's front, hands in front of it's face when they were trying to look at it's nose & lips. Turning it's head when they were trying to look at the spine & putting it's hand across the chest when they were trying to look at the heart. I had to walk around the hospital for 20 minutes to try & get bubs to move & also kneel on the bed with my bum in the air to get them to move! 2 hours we were in there & they said we might have to go back the week after. I have a consultant appointment next week & if the pics aren't clear enough I'll need another scan. My hubby reckons we're having a girl cos he says it's as stubborn as it's mum. We're team yellow, so we'll see if he is right in June!
