Ladybug's mistaken identity

Cristian was looking at a book of animals when he starts pointing at one and saying "acha, acha!" The mom starts laughing and I look at the picture and it is a ladybug. The mom sees my confused look and quickly explains: "He is saying cucaracha". (Cucaracha is coakroach in Spanish.) As a good parent educator, I assure mom that it is good that he is practicing language and trying to identify pictures in books... Even if he thought he was looking at a different bug. DH
