In thinking that my relatives should show some interest in my ds as well

[tankini]

I have been fed up for sometime but ds was the only child in our family until about three years ago when my older sisters grown up children started having children of their own. My ds is now 9.
Ds was never really given that much time tbh off my extended family.
I feel as though I am probably been unreasonable really but I can,t help these feelings of anger when the younger children in the family are given so much attention, and are always been brought presents off holidays etc, and on trips out.
It has happened quite frequently of late were soembody has been on holiday and they have come back with a gift for the two younger children but not a thing for ds.
The items are not given out in front of ds so am not sure if I have any right to feel like this but still I do.
Also when we are all out loads of attnetion is lavished on these two younger children and nobody really talks much to ds.
We have been out on a family outings and presents have been bought for the two younger children and ds has been left out.
I really feel like saying something to certain members of my family about this.
They also get so much more spent on them at christmas, birthdays etc. AIBU.

It shouldn't happen, and it is terrible that it does.

Don't try to change them, as thoughtlessness on the level you describe is impossible to combat. Don't waste your time or emotional energy.

Just spend your time with other people who make you and ds feel wanted and loved. It is the old 'family you were born with' vs 'family you've chosen' situation. Choose to be treated better.

I think it will be difficult to change this behaviour. I think if you tie yourselves in knots over it then your DS will be even more hurt by the treatment of the little ones and his exclusion. Are there particular relatives that are leaving him out?

This isn't acceptable. My parents bend over backwards to be fair and equitable - sometimes to an unnecessary degree.
