I have a lovely dear friend who could well have written your op almost 20 years ago.
Very intelligent woman with great career not really a baby person...
Had it all planned out, baby was going to nursery at 2 months no matter what and she'd be back at work and no longer bored, stuck at home etc...
She couldn't do it! Spent the whole of the first day back at work in bits and ended up asking to take longer mat leave, agreed to work the rest of that week until cover could be sorted, but then went back on Mat leave and when she did return, she went part time.
She also wanted 2 more DC which she's had and she thoroughly enjoys being a mum - as well as her professional role which she has long since returned to doing full time.
I'm not saying this WILL be you, but the truth is you cannot know really how you will feel about parenthood until you are a parent.
Can work the other way too, I've another friend who initially thought she wanted a big family, was from a big family herself (so not necessarily rose tinted glasses) but had a horrendous time being pregnant and while she loves her child, she's found parenthood really tough for various reasons and so decided to not have more.
Personally, I'm not overly enamoured of the young baby stage. I'm a weirdo that likes the teen stage! I adore dd and quite enjoyed the baby stage to a point, there are pros and cons to all stages, I hated the late toddler to primary age point (they think they're more capable than they are, lots of mess and mistakes, plus endless bum and fart jokes!), teen stage much more interesting conversations, can enjoy more adult activities/entertainment, quite independent even 😱 occasionally helpful! But yea could live without the hormonal crap! But then I can be just as bad there!
Not all women, even mothers, are that fussed about babies. It's a short lived stage too.
BUT you need to be honest with yourself. If you really don't want a child having one would be a TERRIBLE idea, but to be blunt at your age you need to decide one way or the other ASAP.
You mention in a post unpredictability etc - that's far less the case with your own child. You can "read" them better. You'll know if your child is a hider/toucher/bolter and will figure out management strategies.
Re c section - I had an emcs it's major surgery, quite debilitating and not the easy option at all. Longer recovery too which could impact return to work plans. Plus again you might well feel differently once actually pregnant.
I thought I was too much of a wimp to contemplate a natural birth, but my mum correctly predicted that once pregnant that would be my preference. Indeed I didn't even take any anaesthesia until I knew I was looking at an emcs and it was a LONG Labour (28 hours). But honestly it wasn't that painful I found and generally speaking vaginal birth is better for mum and baby and quicker to recover from if there's no reason not to.
I agree adoption DEFINITELY not appropriate, adopted children need MORE parenting not less.
Lots to think about op.
