I have one brother, who I am not close to, but we sporadically keep in touch via his wife. He has 4 grandchildren, 2 teenagers and 2 younger ones from his 2 children. I send the grandchildren birthday and Christmas gifts, usually gift vouchers, and my grandchildren receive vouchers in return. My daughter always says thank you for the children's gifts, as she has been brought up to do. However I have not received a thank you from my niece or nephew for their children's gifts for about 4 years. This really annoys me, as just a short text message would do.
Do I stop sending them gifts? This would be the end of my relationship with my brother as my sister in law is extremely prickly, and would take great exception. Do I explain why the gifts are stopping, hoping that she would take her rude children to task, because I really don't think she would. I don't feel inclined to keep spending money them, as it cost about £100 this Christmas with birthdays and Christmas gifts. What's the solution?
