Rosie must go to hospital for heart surgery. She is a very positive little girl and enjoys her new pyjamas, packing her bag, and the fact that mum and teddy are going too. She doesn't like having blood tests, though, and she realises that mum is worried. Lots of procedures are shown in some detail, and as Rosie is in hospital for some time, we see her cards and presents and are told about her visitors. When she can finally come home, there is a party with chocolate cake. A truly outstanding book with delightful, warm illustrations. Highly recommended.
