I just wanted to get an idea of what is common out there.
All my life I've always been surrounded by gift giving and birthday parties so when my brother got married it was only natural for all of us to celebrate and acknowledge my sister-in-law's birthday as well.
Needless to say I'm a big gift giver and birthdays are a big deal for me whether it's mine or not and it wasn't until I met my husband that all of this changed.
We've been married for 5 years now and my in-laws have only celebrated my birthday once out of those 5 years and only because I mentioned it to my husband about them not even acknowledging it. After all I am part of the family now. Right?

My brother and sister in law don't acknowledge my birthday much either. On rare occasions they'll write on my Facebook wall or text me and that's fine by me.
I would be okay with just an acknowledgment since I am part of the family. I'm not expecting anything big. But what gets me the most is that they don't even give my LO any gifts on her birthday! It's just sad for me to think that her own family won't spoil her. FYI: this is their first and only grandchild/niece.

So is this common? Or do your in laws acknowledge and celebrate your birthday?
