Almost sitting up!

I am trying really hard to beat Sam at everything and so far I am winning (apart from sleeping through the night which he won hands down!). Not only did I roll over much earlier, (and also got my first teeth first - see later post!) but I am also nearly sitting up (Sam was around 9 months before he was able to do this). I am not quite sturdy enough to be left for long, but I am getting the hang of it!
