Am I being too sensitive regarding presents?

I'd stop. Put the money towards ur own kids. It's the principle of it more than anything, that ur brother can't even be bothered to make the effort to get a card for his niece/nephew. Who goes to a kids party and doesn't even take a card! Being male is no excuse

To not even bother bringing a card is really rude

I’d say it depends on your relationship with your nieces and nephews. If you are close with them I’d continue to give. But if not, I wouldn’t bother anymore! X

To be fair I do think this is a 'bloke' thing, my partner wouldn't bother anywhere near as much if it wasn't for me organising gifts for his side of the family. Although I do think he would give a card with some money in to show willing.
It's a tough one but I think you should maybe stop giving and just give them a card, although I appreciate you probably don't want the children to miss out, I'd be the same but it's not fair that they don't give back to their niece and nephew now they are here xx

I wouldn't take it out on the kids, it's not their fault and that's who the giving is really for. I'd Definitely have a conversation with your brothers and maybe give them some gift ideas.

I wouldn't buy for them. My cousin is like this, my daughter is 4 yrs old and the 1st present since she was born was a 80p selection box last Christmas! She never receives cards or even a text message to say happy birthday or merry Christmas, so I don't buy or do anything for their kids who one is in college and the other yr8/9.

I wouldn't stop, it's not the little ones fault and they shouldn't pay the price. However I wouldn't go all out and probably get them something small. Definitely have a conversation with them and tell them how it makes your little one feel

I would actually talk to them and ask if "we" are stopping presents, as you noticed they did bring anything for your children and you want it to be fair on ALL the children. I am assuming, but do your brothers have partners? I would never let my husband turn up to a kids party without a gift, even if I wasn't going.

My brothers are both single now, probably as a result of their lack of independent thinking re stuff like this.
I think what's more frustrating is my daughter is a rainbow baby after multiple losses, so she's super special to us. I can't imagine going to a kids party, eating and drinking, taking a party bag for my kid, knowing I haven't even bothered to buy a card.
I'm not 'close' to the kids, but would feel rubbish buying my sister's kid a present (she always makes an effort) and not my brother's kids.

I'll mention it when I see them next as I do think it's naughty not to even get a card.

My brother has 5 kids. They are all adults now. As they turn 18 I stop buying them birthday gifts, I still do Christmas though, just something small. I've been buying them gifts since they first came into my life, the first being when I was only 12

This year he totally ignored my son's 5th birthday, not even a message to say happy birthday (I still message his kids every birthday to wish them a happy birthday). He didn't forget. We went for a meal for my mum's birthday a month later and she asked him about it, he just turned away and started talking to someone else. I was really annoyed. My 2 year olds birthday came 3 months later and my nephew appears on the doorstep with presents for both, with gift receipts dated the day before and Easter eggs (2 weeks late) I'm still annoyed and haven't really spoken to him since January when it was my son's birthday that got ignored and I probably won't by his kids Christmas presents anymore either
