Feeling baby move

Katie • 1st baby 👶🏼
So last night I couldnt sleep I just couldnt get comfy, I'd woken up and turned on my side slightly lying on my tummy and I swear I felt the baby move as if it were repositioning so I moved back onto my back and felt a slight movement and then nothing! Don't think baby liked me lying on my tummy! 
It was definitely different to the little flutters I had gotten a couple of times. I know I was half asleep but I definitely felt baby move!
