This thing is awesome! My husband and I pass it back and forth between each other when we're taking shifts with the baby. Keeps track of last diaper change, last feeding, how long baby has been asleep, and we use the last button for how long she's been awake but you can use it for timing medicine doses or whatever else you need it for. It's back-lit so you can read it in the dark, and the top part with the logo is actually a flashlight. Amazon has it for $15!
