A new baby - any recommendations for 2 yr old?

[Pumpkin20]

DD has just turned 2 and will have a new sibling in December. I would be grateful for any recommendations for books that talk about new babies / being a big sister (or brother) / what is happening inside mummy's tummy and so on.

Many thanks.

There's a house inside my mummy is nice - lovely pictures and amusing rhyming verse ("if I had a house in me, I'd feel quite poorly too"!). We also liked 'I want a sister' (the Little Princess ends up with a brother, as did my dd) and a Topsy and Tim one about a new baby which touches more on what they do when they arrive (cry, have their nappies changed, sleep...).

There's a house inside my mummy. Za Zas baby brother (Lucy Cousins) are both nice books! Also the Topsy and Tim one too. It was nice to see the mother breast feed too!
