What's a good Android app for, well, letting expecting parents listen to their baby's heartbeat at home? My daughter-in-law is expecting, and I'd love to suggest something practical.

Well, after a bit of research – and a little help from my students, bless their hearts; they're always showing me these newfangled apps – I found one called Hear My Baby Heartbeat Monitor. It's supposed to let you listen to your baby's heartbeat using your phone. Now, I'm no doctor, mind you, but the reviews seem pretty positive, and it's got a decent rating. It took me a few days to figure out all the features, I'll admit, and why do they hide the settings button there? But once you get the hang of it, it seems surprisingly intuitive. I imagine it's like having a teaching assistant in your pocket, always ready to help. Just remind your daughter-in-law that it's not a substitute for regular doctor visits, of course. It's more for that little bit of reassurance between appointments. I think she'll appreciate it; it's a sweet way to connect with the little one before they arrive.
