I am looking for some song ideas for my son (10) and I to have a dance to as well as for my daughter (9) and my fiancé. We haven't decided if we will do one song or individual songs. Suggestion would be wonderful.

We would like to include my two children into our ceremony and would like to give them something special. My son will be 10 and my daughter will be 9. Any suggestions or ideas would be greatly appreciated. Thank you.
