I am in a better financial position than my siblings and have always sent birthday cards and presents and as they have got older cheques to nephews and nieces. Last month I sent a cheque to one and texted to see if had arrived. Text I got back was "yeah, just popping to bank" So no thanks from my sibling or the older teen concerned. Another birthday this month so I sent another cheque. Heard nothing for two weeks, then a text saying I'd made a mistake on the cheque and saying if I sent another could I make it payable to (adult aged) child directly. Again no thanks 
. Last year I forgot to sent a card and present to my other niece who I hardly see, and my mum and sister kept emailing and saying it had been niece's birthday. My siblings never hardly ever send anything, not even a card,when it is my children's birthdays. It's irritating me now that they don't even text a thank you. I think as well it's on top of how inhospitable my family is if we visit. No where to sit and no food offered if we go there. And yet they rarely want to visit me where I live which is only just over an hour and 20 minutes away...
