Today Greyden was in his bouncy seat and started fussing. Krew went over to look at him with Dave, and Dave told Krew that Grey was sad.
"Sing him a song?" Krew asked.
"You want to sing him a song?" Dave said. Krew responded yes, so Dave told him to go ahead.
Krew proceeded to sing him the entire song "Twinkle Twinkle Little Star" all by himself. When he was done, he blew Grey an air kiss and then walked away.
Sweetest thing ever. It's looking like he may be a pretty awesome big brother. :)
