DS just turned 13! Big deal birthday! My parents FaceTimed him, both of my brothers also Zoomed with him, sent cards and gifts, etc. He felt acknowledged on his bday. He is the oldest grandkid on this side of the family which may make some difference. They asked about his day, etc., just normal family stuff.
DH's family made not a peep on his birthday. Grandparents sent a gift last week and did text. His siblings completely forgot/didn't acknowledge it at all, despite being on a family text chain where they share tons of random photos etc. I'm used to this because it happens every year and didn't expect this one to be much different, but for some reason this year DH is really annoyed (he said this to me privately, did not voice in front of DS), and DS commented, "Hey, how come XX and XX" never called? He noticed it too!

That makes me feel sad for him.
I think DS doesn't much care but DH is sad. He has always felt his family is out of the loop and not interested and for some reason this is hitting him hard. WWYD? I have said to his parents before that it'd be great to hear from or see them more, but...never happens.
