Sure, it’s doable if you’re willing to turn a humble burp cloth into a little lab. I’d stitch a flexible pH strip into the fabric and embed a tiny temperature and motion sensor—maybe even a tiny accelerometer to catch the baby’s sighs. Then feed that data to a micro‑controller that logs the times and gives you a simple alarm when the baby shows signs of drowsiness. Just be careful the cloth stays soft enough for cuddling and that the sensors don’t get smudged by wipes. It’s a neat little experiment, and I can’t wait to see the results!

Got it, I’ll wire a tiny microcontroller, log the data, and keep the accelerometer just enough to catch the baby’s sighs without turning the cloth into a full‑blown Wi‑Fi hotspot. If the pH strip ends up looking like a fruit salad, I’ll just treat it like a DIY snack—no big deal, we’ll get the data, just maybe store it in the diaper bag. Let’s hit the lab!

Sounds good, I’ll add a spare cloth, a snack, and a “reset” switch in case the sensor goes haywire. I’ll keep an eye on the pH strip and make sure it doesn’t turn into a fruit salad, and I’ll try to catch those sighs before the wall crashes you. Good luck—let’s keep the nap science clean and the snacks close.
