I personally do not wish to have my LO share their birthday with a holiday, though if she/he came that day I wouldn't complain as long as she was healthy it would be my wish to have LO have their own day. I'm due on the 18th, so its a big possibility and for the baby pool that was the day I picked just because I would laugh.
I grew up sharing my birthday with Good Friday, within a range of 3 days normally so family always did things for Easter, and my birthday was always just part of the celebration with the only choice being the cake, it kinda sucked big. So I hope that LO wont have to have that issue.
Just curious - Easter ranges by over a month (March 22 to April 25), so I can't imagine how your bday would always fall so close to Good Friday. My mom, MIL, and now DD all have bdays that fall in that range, but it's really only once every 2-5 years that their birthdays coincide with the holidays.
However, I do agree with you that having a birthday on a holiday could mean joint celebrations. Valentine's Day is a little different, though, since most families don't get together and celebrate it like they do with Easter, Thanksgiving, or Christmas.
I'm due the 16th, but I doubt I'll make it to the 14th. Even if I don't get HELLP, my MFM said that the chances are fairly high that my placenta will develop problems before my EDD. If I do make it to the 14th - awesome, especially since Valentine's Day isn't really celebrated where I live, so it's nbd.
