Totally inappropriate for someone representing the people of United States of America at a State Funeral!   Where was the White House Chief of Protocol?  More importantly, where was Obama's sense of dignity for himself, the country, and the people he was representing?   Michelle should have taken his toy away from him and slapped him on the wrist as is done with antsy kids.

Castro hand shake?  No surprise there --- he just didn't  think of how this could be perceived or more than likely ---- he just didn't care.
