You seem very insistent on telling me how much of an impact having a child must have on my life, when I’m the one who is the parent, and I’m telling you that not that much has changed from the 20-odd years of adult life where I was childfree.
Obviously, it would be different if I had lots of children, or was a single parent, or if DS had significant additional needs or a serious illness or we were struggling financially, and obviously it was more time-consuming when he was a baby, but my life as it has been for the last several years is far less confined than that of friends who have pet animals.
I travel for work and go on holiday much as before. Since the age of seven, he’s not attended a school with a uniform. We don’t live in the UK and there’s much less of a taboo on taking children out of school in termtime for holidays, so that’s not a constraint. It’s been years since he needed childcare, and our jobs are flexible enough to have needed fairly minimal amounts of it. I breastfed, so no formula. Friends passed on clothes from their children when he was small. Now he’s a teenager, he lives in repellent but inexpensive tracksuit bottoms etc. He goes to a school we can almost see from home, so no lengthy school runs.
I have friends with pets who almost never go away because of the cost of kennels or pet sitters, and friends dealing with prohibitive vet bills. I have a good friend who can’t be absent from home for more than about three hours because her nervy dogs go barky and crazy. If she goes away for a weekend it’s always to the same holiday cottage because it suits the dogs. Other friends are up at 5.30 year round because their dogs need a long walk before they go to work. And that’s not even mentioning the ones with horses.
At the moment for me, having a pet would be far more constraining than having a teenager.
