My oldest sister, who is twelve years older than I am, became a grandmother for the first time, over a year ago. I swear, this has brought out something in her that has made the whole family miserable. (By the way, my sister has always seemed to be a reasonable and stable person--until now.) Of course, we all love the new baby, but my sister's love for her grandchild has gotten way out of control. For one, she's horribly jealous of the other grandmother. Also, my sister goes ballistic if she doesn't see the baby for even four or five days. She spent months talking about how she was going to have Christmas Eve "for the baby," putting up hundreds of dollars of decorations (she told her daughter nothing about these plans). Well, my niece (her daughter) ended up not coming to her house for Christmas Eve, because the baby was crying so much at home she dared not take him out. My sister went crazy over this, and basically ruined everyone's Christmas because of it, bitching and sulking about it for days. Didn't matter that she got to spend all of Christmas Day with daughter and baby, there was no pleasing her. My sister has said that her life is crap, but that the new grandchild is "the one bright spot that makes living worthwhile." The fact is, she has a good marriage, a good job, loyal friends and a beautiful home. 80% of conversations with her are about the baby. Now she's convinced that her son-in-law is trying to keep her from seeing the baby (he isn't), and she's constantly saying, "I have a right to see my own grandson!" Obviously, she has issues! But I have two questions. 1) Does she have a right to see her grandson? I mean, she's not his mother. She already sees him a minimum of once a week, sometimes more--we all live in the same area. It's not as if she needs visitation rights... 2) Have any of you dealt with anyone like this? I love my sister, but she's become such a mess over this, and she's become a total drag to be around. Frankly, I don't know why she even has a problem, but she obviously has a big one, that should be dealt with through psychiatric care (although I know she would never go). Thanks in advance for any insights.
