The Petit Boum 'spy' range of bottles has been specifically designed to encourage the development of speech and language.
Tip, turn and shake the bottle, to reveal the different animals/characters hiding in the bottle. Discuss the names of the animals, what sounds they make and what colour they are. This range of bottles comes with a fun activity attached to the neck of the bottle - tick off each item/animal listed on the checklist to ensure you've discovered them all!
