Lulu and the Flying Babies by Posy Simmonds
Lulu doesn't want to be stuck in a museum, she wants to play outside in the snow! She sits on the bench and sniffs. Before she knows it the flying babies have escaped a painting and swept her off her feet. Lulu is flown into a whimiscal, magical adventure through a world of pictures, meeting Kings, growling at tigers and getting lost in the woods.
