I'm 36 and have 3 kids. My sister is 40 and also has 3 kids the exact same ages but mine all came a few months earlier. I also gave them their first grandson. But despite the kids being the same age and me giving them their first grandson, they have literally spent in percentage wise. 90% my sisters kids and 10% mine. My sister in the first 5 years of the kids lives lived very close to the children's grandparents.. ie 1 mile away and I lived 6 miles away. So distance isn't really the issue as both drive, and in the past my brother had given them their first grand daughter and she lived 25 miles away and was seen just as much as my sisters kids. After too many years passing and me just working hard, my kids and my wife were asking me why they would do this. That broke me as a father and the mission to find out why begun. After months of trying to tell them it's unfair and affecting my whole family,( Grandma denied it all and was even proved to be a liar by my daughter, as she had the photos and texts to prove it off her cousin. My sisters daughter) they started to do some more with my kids. After a little while though it just went back to the old ways and even worse, my sister now lives a mile from me and thats 5 miles from them. But they won't even drop by after seeing her kids. It's got to the point where my kids get messages from them and they say to me( I don't want to reply as I'm hurt and know this is the best were going to get.... but why dad)36 year old man now broken hearted again and crying to his beloved wife(How can they treat them so differently) my sisters kids have hit grandma, shouted at her and been very spoilt brats around her. On the very few occasions they have my kids they always say(OMG your kids are so nice and polite and great with each other) So why on earth would they neglect them. My son is only 14 now and is a payed youtuber and has had poems published in books and is an all round bloody nice lad I'm so lucky to have. My daughters are 13 and 6 and havnt quite achieved great things yet but are very strong powerful young girls with great minds. So why on earth would grandparents not want to spend time with the kids who would be every grandparents favourites on the sly. This has lost me 1000s of hours of sleep, numerous anxiety attacks, crying whilst just driving to work,questioning if I'm a problem or my wife. No reasons to at all dislike us. So can anyone on hear tell me why grandparents would be so one sided its shocking and easy for a 6 year old to see. I need an answer or help of some sort to get my own life back to normal. And 8f this has happened to anyone else, how did you get it to be fair forever. Thanks in advance. David
