Family going crazy over baby name

Sarah
My husband and I have been telling everyone from the beginning that we want to pick out a few names and decide his name when we see our baby's face. And we don't want to share our ideas because we don't want anyone's opinions. But his family had been very pushy about giving us suggestions we didn't ask for and asking us what his name is even though we keep saying HE DOES'T HAVE ONE. My SIL for a while kept calling our baby Ethan even though I told her I don't like that name and will not consider it. With all the hormones I'm having a really hard time not screaming at people to STFU already! Anyone else having issues like this?
