S.H.
She is Narcissistic.
TELL HER THAT THE MONEY YOU MAKE FROM YOUR NANNY JOB... IS BECAUSE YOU HAVE HAD TO HELP HER, FINANCIALLY. And that if you did not have this job, then you would have no income nor any money to help her with. AND that, you don't even have to use your money from your JOB, to help her.
She is a Mom. Those are her kids, and it is up to her to make her own kids, happy.
She is not a victim, but acts like one.
And she is not responsible.
Some kids, do not even have.... Grandparents. But they are still happy.
Tell your daughter, that it is up to her, to grow up.
This is your Job.
And you can't even save your money, because you have had to help her.
Tell her the blunt truth.
TELL HER, point blank, what life is.
She is 30. Good grief.
AND she even got FREE BABYSITTING from your 17 year old.
ALL last summer!
REMIND HER OF THAT.
And, what kind of "fun" summer was that, for your 17 year old? He/she had to "work" and babysit! He/she didn't have, downtime or his/her own... free time to enjoy summer or with his or her friends.
REMIND your 30 year old daughter, of that.
Her YOUNGER.... much younger BROTHER/SISTER babysat HER kids. Her TEENAGE sibling... babysat HER kids.
And what was SHE doing all that time??? While you and your 17 year old teen child... babysat HER kids??? ALL summer?
