.. who have failed to do anything about my children's birthdays.
Not a card, certainly not a present, even late. Even after I had a conversation with my brother's wife AFTER the events about what would have been appropriate presents to bring when we saw them a couple of weeks later, nothing.
In fact, one of them phoned on the day and I said "have you rung to say Happy Birthday to your nephew" and he said "er.... yes!" in the manner of one who had no idea it was said day and had in fact phoned about something else entirely.
We don't live near each other, I make a lot of effort to make sure that my kids know who my brothers are, who their kids are etc etc. We don't see each other often but my kids are always told who they're seeing and who they are when we do.
I just think a card twice a year (doesn't have to be on time, even) would be a nice gesture to say "I remember who you are".
My DSs birthdays were in Feb and end of March, I've just seen one of my brothers (and discussed them bringing presents for the boys and given suggestions etc etc) and NOTHING
It's my birthday soon and I know I'm going to get the "Happy Birthday Sis - sorry, forgot to send you anything" phonecall, which is fine.
But not fine for my kids. They are 4 and 2 FFS and soon they will start to notice that their uncle on the other side bothers and they don't.
