I've never been able to sleep as deeply as I did before having her, my mum one of the most laid back people you'll ever meet on this kind of thing says she STILL doesn't go into a deep sleep in case one of us calls needing her - we're all in our 40's!
In my case I also had the joy (!) of a child who didn't sleep through until...
...she was 5 YEARS old - yep years, not even kidding! And even then she was an early riser (I'm talking BEFORE 6 am every day) until she was 12/13! She STILL isn't a good sleeper I doubt she ever will be but she doesn't wake me now.
I have a c section scar and "apron" of skin and stretch marks - yep 18 years later! Even when at 2 points I got to weighing less than I did before pregnancy the apron was still there so it's not just down to weight, before anyone says.
"I forgot to mention permanent piles!" Oh yes! 18 years op and I STILL have the piles from pregnancy! Quite honestly the pain and occasional bleeding is nowhere near as annoying as the itching when they flare up!
My boobs are huge - they were barely existent pre pregnancy. It's expensive and difficult getting bras to fit, they itch and hurt and make buying clothes generally really difficult.
My hips have never been right since pregnancy either, my shape has changed and they hurt constantly.
I've been skint her entire life, having a budget I keep a very close eye on is my default now.
Definitely agree when kids are little you can't do ANYTHING without major military planning which is a TOTAL pita!
I had visions of being a lovely relaxed earth mother - then I had dd! She DEMANDED routine from the very start and woe betide us if we tried to vary it in the slightest! Even 5 mins late for a nap = sleepless night that night. At least one if not more.
Late meal/snack resulted in screaming fury and more than likely a poonami to deal with! You have NO IDEA just how much a poonami can cover! I had times where it resulted in not only a covered in poo dd and full change of clothes for her, but where it necessitated an entire change of clothes and shower for me AND a complete bed change! You would not think so much shit could escape from one tiny human!
Colic/teething etc - sleepless nights spent pacing while trying to calm a distressed and VERY noisy baby and thinking the neighbours must HATE US! And your heart breaking because you've done all you can to help and they're clearly still suffering.
Toddler tantrums over the most bonkers things, usually in public where you do find yourself thinking people must think you're awful. Not to mention being kicked, hit, scratched even headbutted while you try to remove them from wrecking an entire display of glass jarred pickles or similar.
CONSTANTLY having to watch them so they don't leap off the top of a slide, bolt into traffic or try and force feed the neighbours dog chocolate buttons is EXHAUSTING.
Preschoolers who constantly ask "but why"
5 year olds who try to discover if the bed is as good as a trampoline either wrecking the bed or bouncing into the wall, constant scraped knees at this stage - you'll need shares in germolene and Elastoplast!
"My son leaves his toys everywhere and im forever tripping up and standing on them." Yep the sheer agony of standing on Lego/barbie shoes/meccano/toy kitchen bits barefoot in the middle of the night and trying not to scream out!
7 year olds who eat too much at birthday parties and then spend an hour non stop on the bouncy castle - then vomit all over the car on the way home (seriously try getting vomit out the area where the gear stick is located!)
10 year olds who wander off while playing and put the fear of God into you thinking they've been abducted or in a ditch somewhere...then you find them in a street 2 streets from their "boundary" cos they followed a kitten!
High school years full of angst; body image issues, academic concerns, friendship squabbles or even outright bullying, sports injuries, lost clothes, broken and lost mobile phones and other items, then romantic heartbreaks (if you think it's hard dealing with your own love life it's 10 X harder watching your child's heart be broken)
