I have a bit of a dilemma. My DSCs are now mostly young adults and not living with me and DP. However they did live with us for about 6 years, including my now teenage son, their step brother.
I had a DS with my DP who is their half brother (and who will be 3) and it is his birthday next month. They don't really have a relationship, DS doesn't know them very well, but they would want to feel part of his birthday.
This year however all my DSCs didn't do anything for my other DSs birthday (which was last month). Not a card, a text, anything. He was pretty upset. Admittedly I didn't do the big 'reminder', and DS didn't have a big 'party' as he's a bit teenage now, but still. I used to practically do everything for DSCs, buy the cards etc, but phased this out as they are young adults now, however they did hear about it afterwards and still made no apologies or well wishes. We always remember their birthdays.
Of course I will invite everyone for half brothers DS birthday, but it feels bit rubbish for elder DS for his little brother to be made a fuss of and him virtually ignored. I don't want every year from now on to be only the DSCs recognising their half brother but not their step brother. I even thought about whether I could make it a joint celebration, but that just feels a bit strange. What to do?
