Humanity also “got by” with high rates of disease and infant mortality.
Reducing real risk— keeping kids safe-- matters. There are degrees to this, of course, and people will disagree about what is reasonable, but just because the species has survived up to this point is a dumb way to shame people for being careful and observant.
Baby cameras are amazing and apparently something you haven’t given much thought to since you’re glomming them into a group with motion sensors (huh?) and wipe warmers (wtf?). When my daughter wakes up in the middle of the night crying, I can check if she’s puked and needs some help or if she’s just a little upset and needs to calm herself down. It’s a convenience, sure, but it’s also a tool for helping me to help her be more self reliant.
