New look

So I was getting a little bored with the grey and white look of my blog so I decided to brighten it up a little! My new banner I have made using a photograph Mia had taken when she did some online catalogue pictures. I love the photograph as it was when she was becoming confident standing and although you can't see in the photo those clothes were huge and pegged at the back and now they finally fit! 

I would like to try and group posts into pages like: pregnancy, Mia, food, home decor etc so any advice on how to do this would be much appreciated! I did try and follow some online instructions earlier but it didn't work :(
