Big Day

We've been trying for weeks to figure out what "ishish" means. Today Chomper was pointing out Dada in a family photo (as often happens when he's out of town). I also told him that Mama and Chomper were in the photo. After that he said "ishish". To be sure, I pointed to him in the photo again and asked who that was. He repeated himself. Wow, he can say his name!!
