Okay so I'm 11w3d and my husband and I are trying to decide on baby names! We don't have our girl name decided yet but we decided on "Matty Grey" for a boy name. We both LOVE it but when both of our parents asked about names they said that our so would be made fun of for that name and we're asking for it. Do you guys think a boy named Matty is wrong or is it just them?
