how to tell??

Sabrina
So my son is 7 now and has voiced that he does not want any siblings. We haven't told him that I'm expecting yet. I'm looking for some fun, creative, exciting, etc way to tell him that he's going to be a big brother. I don't want to wait too long to tell him bc i haven't been myself lately & I/we want him to feel involved. Anyone have a similar issue or any ideas ??
