Tummy to back flip

We think that our little Josie just did a tummy to back flip. She was on her tummy, when she pushed and kicked and rolled over. Unsure, we put her back on her tummy to try again. But she was already very fustrated now, since she does not like tummy time. Yet. 

(She's on her cot supervised by both of us and it's a very short time for a photo)

Checked online and also with some mummy gfs, the average is around 3 months for this stunt. 

Today LO is only 7w3do. Not even 2 months old. Hmm... A fast learner? Haha.. Applause for our little Josie!
