A 5-year old Michigan boy showed up at the courthouse in Grand Rapids, Michigan, on Thursday for an adoption hearing with his foster parents, and his entire Kindergarten class.

Michael’s mother told CNN that her new son’s teacher, Mrs. McKee, floated the idea to her one day when she dropped Michael off at Wealthy Elementary School.

McKee knew the adoption would be finalized soon, and the two agreed on how to make the big day particularly special for Michael.

Here’s more from ABC 13 News:

According to Michael’s adoptive father, he shared that the judge said it was the first time she’d ever hosted a whole kindergarten class for a hearing in her courtroom.

Michael’s new father and mother have been married for nearly 10 years, and he’s been living with them as a foster child since last Thanksgiving.

“We didn’t have any kids prior to that, and things got pretty chaotic in a hurry,” his father said.

Look at that smile! Congratulations to the new family!
