Is it selfish?

Rachel • baby number 3

This is my 3rd and last baby- we also have 2 step kids so this is it. And many many years ago my sister found out that she could never have babies of her own and so I thought she'd want to spend more time with me and my kids- being that I'm her only sister and the only one who has children. But she's always distanced herself from us saying it's too much of a painful reminder of what she's always wanted and never will have....ouch, I know.

She's the godmother of my other 2 kids and still doesn't have anything to do with them. A fact I've just come to terms with.

With my other deliveries my mother was my other support person aside from my husband to be in the delivery room with me - and a big crutch I've come to rely and lean on in that time - as she herself had 4kids.

We had asked my sister to come and babysit (which she's never done or offered to before)

while my mother, husband and I go to the hospital to deliver and she agreed to it, without any hesitation. So I informed my mother of the "game plan" and she said, " I'm willing to stay and babysit and let your sister take my place with you. Seeing how she'll never have a baby this will be the closest thing she'll ever have to it".

Stunned I didn't say anything, except. Okay?

Like they had already been talking about this for some time.. no one even asked if it's what I want... hell, I see where she's coming from but we're not close, At All! Do I say screw it and let her come in place of my mom? Or should I put my proverbial foot down and say no?
