My partners parents came over today. I really like his parents but his dad gave my stepdaughter £20 and my 2 year old daughter a mug that says special granddaughter. The last time he came he also gave my stepdaughter money but nothing for my 2 two year old. I was upset as my dad gives both the same, even though he is not a grandad to my stepdaughter. My stepdaughter is amazing and at only 10 years of age turned round and said she would share her money with her sister. 8 said how kind she was but that it was hers. My stepdaughter also commented the last time my partners dad didn't give my 2 year old anything and said it wasn't fair. I dont care about the money, it's the fact they should be treated equally. Am I being unreasonable?
