All of the cousins know each other. There are grand nieces and nephews in my count. I make sure that each one of them thinks of me as their favorite aunt. How do I do it? I spend time with them, doing the things they enjoy. Our relationships have nothing to do with their relationship with my kids. My family is tight knit and supportive, so that helps, too. Don't you like being an aunt!
Really wish you were my SiL. She gatekeeped DH and I from having a relationship with her children when we were childless. Then she made major productions about the age gap as her kids are 5 1/2 and 3 1/2 years older than our kids - "would've been nice if you had had your kids earlier" - and that they really couldn't be expected to hang out. I was expected to entertain my younger siblings and cousins of any age when I was growing up - there were 30 of them and we had reunions 3x/year. My kids knew that they were expected to entertain any friends visiting with younger kids for at least an hour after arrival. As DH and I would say, "couldn't she expect her son to get off his screen for even 30 minutes" to play with his younger cousin. When her son graduated from HS, he hugged our son, who later said in the car, "I didn't even think he knew who I was."
But back to OP, I would borrow some advice from the PP - maybe take the kid every 3rd time and do something fun. Leave an impression - he will have those memories for the rest of his life.
