You do get used to having less sleep (I haven't slept in past 9 for years and couldn't do it now- most days I'm up at 6am), less time with your partner, less free time.
I was someone who didn't particularly want kids, never felt broody, didn't feel maternal, wasn't bothered either way but didn't really think I had them.
I met someone in my mid thirties who wanted children and took myself off travelling for a bit and had a really good think about whether I should have them all not.
I was lucky in that I wasn't a party animal, didn't have a huge social life, no brilliant career (though I have a good education)to give up etc
Since having DC, I've become rather obsessed with parenting, reading about it, learning about it talking about it. I do find it terribly hard though.
I don't find babies boring- in fact I love babies. I find toddlers really hard work. I'm looking forward to having teenagers.
For me the best thing about having children is the playing and messing about.
The worst is the drudgery (endless washing, food, mess, poos) and the constant stress (sibling fighting, endless noise, tantrums, sleep problems, eating issues, logistics, whining, whinging, demands).
I do love my children but I also know I would have had a good but different life without them
