I have two children with a man who was married before and had 4 children in that marriage. They are now adults in their late 20's and 30's. It's always been strained between him and 3 of his older children. 1 of the 4 older children has a close relationship with him and is very supportive of us and our life together. Our two children together are under 9. They've all met our eldest child over the years. Picking and choosing when to bother the eldest. But I've accepted it for what it is. Then when our youngest came along no one has met them. We contacted them to tell about the safe arrival. After a difficult time after birth we stopped making all the trips to see people and consequently, no one has met our youngest. She's 2 and has not heard anything on christmases or birthdays or in-between. I've always been clear gifts are not expected, but acknowledgement is. Children don't deserve to be punished for adults life choices. 2 of his eldest don't have anything to do with any of us after we've spoken up about our feelings. So that's all been put to bed. But the third of his eldest children continues to send to our eldest when it suits (cards, gifts, money gifts) and nothing for our youngest.
My eldest is aware, we've always had honest, but gentle, conversations about the family dynamics.
I've spoken up previously about our feelings on this subject to each of the older children, with my partner agreeing, and yet this particular older child continues to send to one and not the other.
How would you deal with situation?
