When we went for our NT ultrasound our little man was very sleepy and wouldn't move. The tech had a hard time getting measurements. She kept calling him stubborn. I had the 'brilliant' idea for the next scan to eat a kit kat for breakfast thinking the sugar may help get him active. It did! The tech complained that he was moving too much and asked if I had breakfast. I admitted to my kit kat meal and she went on and on about how I had to be careful about sugar, etc, and shouldn't be eating kit kats for breakfast 😩 I loved seeing him move on the scan though. Worth it IMHO.
