I've pushed to have my last name as part of the baby's last name and my husband is totally on board. Both of our names end in "son", so it's a bit long, but we've decided it's the only way for us to both feel/be included! Additionally, we've decided to let our kid (maybe even encourage our kid) to drop one of the last names if he ever decides he wants to.
Here's my question: right now we are not planning on using a hyphen, but people have said that may get confusing on legal documents. Example: Michael Christopher Johnson Peterson
Note: I don't want my name as a second middle name...it will be the first part of the last name.
