While it may be a true statistic, it seems to dramatically miss the boat. Time spent with a newborn, with an infant, with a four year old, with a ten year old, with a sixteen year old, with a twenty year old are not the same. You can have more interaction, more contentment, more sense of continuity, and more sense of family, in a Thanksgiving weekend spent with your adult child and their family than the entirety of y…
There's a common sentiment on social media that you must cherish every single moment possible with your child or you'll regret it later. While well-meaning, this can lead to parents being guilted into having no boundaries.
Setting aside time for yourself is just as important. It makes you less stressed, helps kids develop independence, and models healthy boundary-setting. For example, spending 5-10 minutes fully engaged playing with your child is much more valuable than spending an hour halfheartedly playing with them while your mind is wandering elsewhere.
Don't let numbers like "only 12 summers" create a ticking doom clock over your head, or constantly second-guess yourself, "did I spend enough time with my kids today?" Parents have enough stress as it is.
I'm not saying you should ignore your kids on the weekdays and only spend time with them on the weekends, just that you should not feel guilty about setting boundaries and taking time for yourself sometimes.
(Also: I do agree that spending time outdoors is very healthy and important, but I consider that to be a separate issue.)
