Cuppatea -- Honestly, if your main concerns are going out at night, doing what you want when you want, sleeping in, etc. and you put these pursuits above caring for your child, then maybe you shouldn't have them.
There's no rule that everyone has to be a parent.
It's sad when I see kids born just because their parents were under social pressure, but who aren't really wanted and are just treated like a nuisance.
I just met a mom-to-be who was already planning on sending her baby away to be cared for by someone else. So (and I know you're joking) but there are people who treat their kids like animals who have to be kenneled.
My Chinese ayi just told me of "hospitals" in China where rich people send their infants for those difficult first months, even though they're perfectly healthy. They basically grow up in fancier versions of orphanages.
A less crazy version is the rich Hong Kong tai tai who has a houseful of servants, who's barely ever lifted her own baby.
Which makes me ask -- why have kids to being with?
BTW, you seem to have a rather odd view that parenthood = loser.
I'm a full-time working mom. I eat at nice restaurants. I have a beloved cat, a social life, an active working life, and am very independent.
And as the baby gets older, she will integrate even more into my life. I hope that, someday, she will be my eating / shopping / travelling buddy.
Of course I've made some adjustments. I deliberately don't have our helper come in the mornings so I can spend a good three hours with my daughter before I work at noon. I do this because it's my great joy. I schedule more lunches now than dinner because I really like catching my baby before her bedtime. But, again, this is not because it's an obligation -- it's because I love it. If I really wanted to stay out, I could, esp. with the childcare situation in HK.
The tone of your message is slightly resentful. The idea of having a baby doesn't seem to make you happy (maybe it does, and it just doesn't come across in a brief message). But if your only concern is that you're "supposed to" feel a certain way, that doesn't seem reason enough to bring a life into this world, and be responsible for 18+ years.
