Yes I regret it. Unlike a lot of people, I found the early years a joy. I had those fabled incredible sleeping babies, straight through from the day I got back from hospital, I had to dream feed. Very happy and smiley, moving onto happy, smiley toddlers.
Then it became clear that they had ADHD. School and home became problematic, although they were still happy (and wild). Then the constant attempts by school to control their twitchy behaviour (never aggressive) caused a negativity spiral that basically depressed them.
Then the anger started at home, the school refusal, the defiance at school. The suspensions, the permanent exclusion.
Home life is shit most of the time. DH and I are still together, just. Obviously we have good moments, but that's all they are, moments.
I think when it comes to regretting having kids, an awful lot depends on what your kids are like.
It also depends on what your parenting style is like, if you give them almost every minute of your day then of course it will be relentless drudgery.
Plus life and parenting has challenges never seen before. Too much pressure, too much social media, too much helicoptering, too much of everything.
