I have been a single parent for almost three years and since then my would have been in-laws have been treating my son awfully, me and my ex broke up when I became pregnant and they seem to be blaming my poor DD for this, I still allow them to see him and my DD whom is older but they make the least effort with him, he did not receive one birthday gift this year and they decided not to come to his party, they also took my DD away for the weekend and didn't offer to take him, I don't want to damage their grandparent relationship with my DD but I also want to say that maybe they should treat my children the same, they are coming to her birthday party, shower her with gifts and my son gets nothing, should I say something? I don't want to start a family argument but I also don't know how to word it which doesn't show how upset I am for my son, he deserves doting grandparents also, he is only little and doesn't know the extent to which he is being pushed out.
