Rolling over!

Since I am such a wriggler, I very rarely stay still for long. Mummy has been putting me on my tummy quite a lot, and the other day I got so cross I arched my head right back and rolled over onto my back! Mummy thought this may have been a bit of a fluke, but twice today I have rolled over! Not bad for 17 weeks and 2 days old! (Mummy said Sam was at least 8 months before he did it and I am not even 4 yet!). Just need to learn to go from my back to my front now!
