Anyway this is my sweet boy Mr. Elliott; he likes Minky blankets, his binky (he gets big feelings and carries it around to help), and cuddling in his parents' knee pits

Stop having kids with an agenda for who they will be. Not everyone wants kids and it shouldn't be a personal affront to your person that your adult child doesn't want their own. The wish of being a grandparent isn't your kids' to fulfill for you. Get a grip!
