Grandpa's noises / Gareth St. John and Colin Rowe.

"Children love laughing about body noises. In Grandpa's Noises, a range of sounds and words coming from body and mouth are explained in a warm and funny intergenerational romp. Children look at life with open, honest eyes but sometimes it takes a bit of thinking and code-breaking to work out what's really going on. Fortunately, for this particular grandchild, while Grandpa's noises might be a mystery to many, he knows just what they mean! For example, "Eyenolessgofurawark" is obviously Grandpa-speak for "I know, let’s go for a walk". "Aaaahhh" means the cup of tea is just perfect, and "Pissphusshawertt" is that sinking sound Grandpa makes when he needs a rest in his chair. And once you know that "Eeeawoscreech!" is actually the sound of a misbehaving hearing aid, Grandpa becomes a lot less scary and even more lovable. Of course some sounds - like the "Fffffffft" that sometimes escapes Grandpa’s bottom, and Dad's - need no explanation!"--Goodreads.
