No family

My wife and I recently found out our home insemination process worked, we’re due 12/11/19! This is something we’ve planned for about a year and very thrilled it happen on the first time! Her mother on the other hand is not so open to it because I have two kids of my own already from previous relationships and she’d rather my wife carry. She didn’t want to. I can’t help but to feel down and it sucks because I don’t have family of my own and I feel I should be thrilled at this time but I can’t help but to feel kind of sad. 😏
