So I have one child and all my three brothers and sisters have two each. We have always set a £20 limit on niece and nephew present (even though I'm spending £40 on each family 2X£20, which I've always been fine with as it is my choice to only have one child) however I found out today that one sibling only spends £15 on my only child when I have already spent £20 on each of his children (therefore spending £40 total). Should I be so annoyed that this was not discussed before I went out and spent the £40 that my son was only getting a £15 present?! Am I being unreasonable?
