Can't crawl, won't crawl!

This morning Daddy was on an early at work, I had woken up when his alarm went off so he brought me in to bed with Mummy, where I fell back to sleep! Mummy wasn't impressed - she could have had a lie in!
Me and Mummy went to the Trafford Centre for lunch with some of her work friends. She left me with them whilst she went to heat my dinner up - I didn't even notice she'd gone!!
Lunch was very tiring, especially as I spent quite a while walking round holding Mummy's hands. I slept all the way home in the car.
When we got home Mummy lay me down on my mats, I rolled over onto my tummy and Mummy thought I was about to crawl...
But I didn't. I cried instead!!
