So , I'm in the process of toilet training with my nearly 3 year old boy. The weeing is going really well but the pooing not so well. He's taken to pooing on the floor and late nights as he's holding it in the majority of the time. He loves books so I'm looking at books to help show and explain aswell as make him feel more comfortable and less nervous about pooing.. but there's so many! What books can anybody recommend?. Thanks
