Yet, she never stopped to say no, don't do any of the cooking, cleaning, or dropping me off! I assume, also, that she did ask for lifts or at the least didn't say no, it's alright I can take myself or get a taxi, it's fine, did she?
She can afford childcare. She just wants to use her friends as free childcare so she can get ratted once a fortnight.
That's exactly what she signed up for when she chose to continue the pregnancy. She's not running to the father is she and banging down his door, you know, the person who is 50% responsible for the child's existence-and demanding he takes HIS child once a fortnight, is she?
No, she's asking for it from friends who have been very clear that they don't want children of their own and enjoy doing things that don't involve or cater to children-who also had zero say or responsibility in creating said child. Do you seriously think that's reasonable? Really?
They didn't choose for her to have this child. Now, she wants to burden them with a choice she made because she doesn't want to put her hand in her own pocket to pay for this childcare. I get that she needs time to herself-don't all parents-but you get that by either paying for it. Not demanding it off people who don't want to do it who have no responsibility for the choice she made.
Also, what are they getting in return for all this childcare and help? She's expecting them to entirely change every social outing to suit her new life. She's expecting them to babysit once a fortnight so she can go out and continue her pre-baby life. So, what's she doing in return? Anything? Or are friendships are one-way street where the entitled parent takes, takes and takes some more and gives nothing back?
OP has supported her in the ways that has probably been very beneficial to her friend-after all-she never turned it down (cheeky fucks never do) and ways that she feels comfortable doing-but that's not enough because the friend can't go out on dates and do what she wants anymore (even though she can she just needs to pay a professional like everyone else).
Also, what's the likelihood of all 10 friends agreeing to this rota? Pretty low. So, someone is going to be doing more than 3 times a year, aren't they? Also, it's pretty likely that in this rota, there'll come a time when one of them can't make their "agreed" turn, and someone else has to cover. Taking more than their alleged "share."
If they agreed to this set-up, it'd only be a matter of time before the fortnight became weekly. Then, it'd be "Oh, OP, could you just pick up my DS from nursery, I'm busy!" and so on and so forth the cheeky fuckery continues.
So, maybe instead of thinking that all of her friends, who had no input in this choice of hers, should bend over backwards for her, you should be saying, "You know what-that baby didn't magically appear out of thin air, I'm sure someone else is 50% responsible for it-maybe HE should be forced to take care of it, too!"
But, I forget, OP and her friends are women, child-free women at that, and women are carers, first and foremost and if you don't have children of your own, your time is everyone else's to do what they want with it.
