Lulu's mum and dad use stories to prepare her for the arrival of a new sibling and make sure they still have time for her and her stories once baby Zeki arrives. So, it is no surprise that Lulu believes every problem can be solved with story - and from bath time to bedtime, she chooses just the right one to read to her new baby brother. Zeki cries a lot but his book-loving sister has the solution; when he's upset, she reads him a funny story; when he needs a new nappy, she reads him her favourite potty book and when he cries in the bath, she reads him her best duck book. Fortunately, Zeki also sleeps a lot too and that gives Lulu plenty time for her own reading.
