Thank you for viewing! This is the picture book "Omu-tsu no Naka, Misete Misete!" (Show Me What's in Your Diaper!) for toilet training. It has a fun flap that you can lift to see inside the diaper. I have three copies of this book, which I received as gifts for my baby, and have kept them unused. I am now selling them. How about it as a birthday present for a 2-year-old? The list price is 1300 yen (excluding tax). Thank you. #PictureBook #ToiletTraining #ToiletTraining #Omu-tsuNoNakaMiseteMisete #PottyTraining #2YearsOld
