My SO wants to name our son after his cousin he asked his cousin if we could use his name he said yes and was happy we wanted to well a few weeks ago his cousin found out that his girlfriend is pregnant and they are due 3 months after us we are so happy for them they told us yesterday that the too are having a boy so now we have to pick a different name for our son and only have 10 weeks until he is here😔
