With his special bubble wand, Lou always knows what to do and how to behave at a friend's birthday party. He knows what to expect (it's going to be loud) and how he should act. He knows that if he can behave appropriately at his friend's celebration, he will likely get more party invitations in the future. This third book in the Lou Knows What to Do series shows children how to be comfortable and successful in potentially challenging situations.. Each social story is written for children in nursery to year 6, including those with differing developmental levels and learning styles. An excellent read for students living with autism spectrum disorders!
