Pop off the rear filter and clean it from both sides then blow out the dryer front to back; lint can pack in behind the screen and around the thermostat where you can’t see it which, yeah keep hair well clear of the intake, since even a quick blockage will spike temps and trip the thermal protector. After each use, finish with 15-30 seconds of the cool-shot to purge heat; if it still trips on high fan/low heat with no attachments, the protector or fan bearings are likely tired and replacement is usually best.
Folding a stroller one-handed while holding a squirmy baby is like a parenting superpower you gotta master. Look for ones with a simple latch that clicks shut effortlessly and and make sure it's stable when folded so it doesn't tip over. that model is non-negotiable if you're carrying it around, think something you can hoist with ease even after a long day. I tried that and it fixed everything but then... yeah, had to adjust my grip a bit.
On walks, I always make sure the wheels are aligned before folding, prevents any jamming. And if it's for quick errands, test how fast you can deploy it too, because unfolding can be just as tricky sometimes. Super handy for those spontaneous park trips.
