Take this as an opportunity to embrace the fact that they noticed and
pleasantly move their thinking. You always win more with respect, humor and
pleasant discussion. Remember to confire with the NAEA publications on
Displaying responsibly. Post what you are doing the focus of the lesson, what
they children are attempting to do and what they are learning. Have the
children write about what they did and post it next to the work. That will
take the "cute" out of the comment unless that is the ultimate compliment of
the viewers vocabulary and in that case "it's a compliment".
Good luck and keep it at it with a smile!
