Has something gone funny with your layout? There is no background to your text box and I cannot for the life of me read your text. I agree that the teddies make it quite 'busy' - perhaps you could leave them but not have the tiled down the whole page - just as a bar along the top.
I'd remove the first post, since you now have that info in your 'About Me' page.
The content looks great - from what I can see of it.

love your blog's simplicity - could you get the strapline (trying to be a better..) all into one line? Or is that just on Google Chrome that the last yada is on the second line?
As to getting more readers on Twitter - first start by looking for other bloggers and blogger networks (Britmums, Netmums, Tots) and following them. If they RT a blog, have a look and start chatting with the other bloggers.
Twitter is interactive - you will need to spend a bit of time on it to begin with then you will start to see a rise in hits. You do have to see it as primarily a place to chat to others, and not a place to advertise your blog - a couple of links a day eg morning, lunchtime, evening is fine. Don't overdo it but don't just post one link and be done.
Try to link to other blogs that you find interesting, and to any news stories or magazine articles. Don't just tweet about blogging, but about other stuff, and react to what others are telling you.
Someone said today, "Be human", and that is the first rule of Twitter. Or second, if the first rule is INTERACT :)
I have a few tips on my blog about this here. Do come and find me on Twitter.
