Introducing Python

A series of board books to help toddlers develop from first words to first phrases by introducing simple word combinations and first experiences.In My Potty! we follow four toddlers and their families as they start their potty training journey. Go to the shop to buy a potty ("let's go shopping!"), practice and try it out ("sit down", "stand up!") then learn what to do after ("time to wipe", "pull up pants", "wash hands"). This book also offers reassurance with accidents, shows toddlers that trying to go without results is still good practice and then celebrates successful potty trips together!With text written in consultation with Priya Desai, a children's speech and language therapist, Toddler Talk features familiar scenes of everyday life with lots of busy toddlers to look at (including a mirror on the final page so they can see themselves).Includes a FREE Nosy Crow Stories Aloud® audiobook! Scan the code, hear the story.Read along with your toddler to build the next step in their la
