My MIL hates our baby's name

Amanda

So we've been wanting a boy for the last 3 years, and instead we ended up having 2 beautiful girls. Well late last year we found out I was pregnant again (totally not planned) and then were so excited to find out it is finally our little boy. We've had a name picked put for 3 years, there's no way we are changing it because we like it and I've always been a "screw your opinion" type of person. Well, SO's mother HATES the name and whenever I am alone with her she always tries to put her two cents in about it. It makes just want to scream, because it's never going to change and it's not that crazy or weird. I feel like boy names are either super bland, overused or ridiculous sounding. When we heard this one is just stuck and I can't imagine anything else. I just hope it doesn't pain her to call him by his name...it seems like it will be 😐 UGH

BTW: His name is Locke (inspired by our mutual liking of Lost)
