Where's Mica?

• "Mica, where are you?" I along with other people have been hearing from Isaak.
• I took just Isaak to the grocery store and he kept yelling out, "Mica...Daddy where are you?"
• Then when Mica was at preschool yesterday Isaak kept walking around Grandma and Grandpa Spiehs' house saying, "Mica where are you?"
