Which one?

Hi. My mum gave me two halves of a cruskit (a new snack I love). They were both so yummy that I couldn't decide which one to eat first! My house has floorboards and it's hard for me to move on them. Today I learnt that I could use the heels of my feet to push myself backwards. That's what I also was doing in this picture. My parents think it's a funny way to move around, but I think it's great!
