Not up to date on baby gear? Neither am I. I had no idea you could get a special timer just for remembering when you last fed, changed, napped, or otherwise interacted with the baby.
I'm not much on keeping track of things. By three days I haven't entirely given up on the chart from the hospital, but everything I write on it is entirely fabricated. I know I fed them sometime. They'll remind me if I forget to do it again. I probably forgot to change them, but I'll remember when they start dripping.
Of course there are people out there who keep those charts for months. They probably wouldn't use the timer that much either, as it doesn't have archives for the truly obsessive record keeper.
I'm still not sure why you would need a timer for something that comes with its own built-in alarm . . .
